While it is true that for plain proxing, pound is simpler and easier to configure, nginx scales better (e.g. when you have e.g. 1000+ concurrent connecitions) and offers a large scale of modules etc. We switched from pound to nginx two years ago, and the decision was right for us.

Re: [AOLSERVER] Virtual hosting
You can absolutely run multiple named vhosts off a single IP with no problem. It works out of the box from I think the first release of 4.x. I think the sample config shows all you need to know about vhosting but if not I'd be happy to help come up with a better concise example. the only caveat is that all the vhosts run as the same server meaning the same user. (I had an idea a while back for how to support multi-user virtual hosting via nsproxy, but it never went anywhere) You can absolutely *not* run multiple SSL servers off one ip, and you never will be able to with aolserver or anything else. This is because the certificate is exchanged as part of the ssl handshake which happens before the web server ever has a chance to see it and respond to any Host: header.

I cheated and doubled up the use of the ns/module/nssock hostname parameter ... which may have been a mistake. In order to specify the default virtual server, you set hostname to one of the values from the ns/module/nssock/servers section.

Dossy wrote: How do people feel about this? Is glob matching wanted enough to incur that per-request cost -- only if you're configured for software virtual hosting, of course. Actually, my company is using a different approach to vhosting (I do this for docroot, but this method could be used here as well). We call Tcl proc for determining vhost-docroot relation. Since it would be WAY too slow to call Tcl proc on every connection, we have an Ns_Cache for storing docroots. There's almost no impact, except for a very small memory consumption. If one would cry over locking, then I suggest a two-level cache - per-thread one (no locking, more memory consumption) and global one. ps. This way we could even use a Tcl proc to resolve vhost-server. By default it would read nssock/servers section of the configuration. Tcl+cache should be faster than globbing on every request :) -- WK -- AOLserver - http://www.aolserver.com/ To Remove yourself from this list, simply send an email to [EMAIL PROTECTED] with the body of SIGNOFF AOLSERVER in the email message.

http://sourceforge.net/tracker/index.php?func=detailaid=812036group_id=3152atid=103152
Reviewing the above bug, there's some discussion I want to raise before
fixing it.
It would be simple to add a new config. parameter which declares the
default server when no Host: header is provided in the HTTP request
for HTTP 1.0 requests. (When no Host: header is provided on an HTTP
1.1 request, this should result in an 400 Bad Request, see Bug #787728.)
In Apache you can declare default virtual host and in my oppinion it
more desired feature than returning 400 Bad Request.
However, what's really interesting is the RFE that's snuck into the
bottom of Bug #812036: glob matching of the Host: header. Clearly,
there's an added performance cost involved in glob matching vs. a
straight hash lookup, but I guess if you're already doing software
virtual hosting, performance probably isn't terribly important.
How do people feel about this? Is glob matching wanted enough to incur
that per-request cost -- only if you're configured for software virtual
hosting, of course.
-- Dossy
In my implementation of virtual hosting within one virtual server (which
I've posted to the list some month ago) we decided to allow wildcard
names for vhosts matching host header. First we try to matchhHost header
exactly then we iterate over hash table and do string match. If you
declare exact vhost then you have optimal solution, if you use wildcards
than you have to do the search.
--tkosiak
Here is the code from my proposal. We've also written code to add and to
remove entries from hashtable and also to declare own function
((*host2vserverPtr)(server, host)) which maps host header to vserver
name. I can repost rest of teh code once more.

It will have to be thoroughly tested but it looks like I will be able to achieve my goal of building some of our required apps in AOLS/Tcl instead of J2EE which will please the boss as Java development is s slooow.
This is so cool it should be a core feature. Thanks again.

by AOLS. I believe this can be done with virtual hosting but I can't
find any examples of how to set it up. If its possible could someone
give me a few pointers. If there is a better way knowledge of that would
also be appreciated.
You can do this with non-standard ns_register_proxy command which
exposes functionality already existing in nsvhr module. Try my patched
nsvh2 from:
http://www.zjednoczenie.com/upload/aolserver/nsvhr2.tgz
When you compile and load nsvhr2.so you should put into library *.tcl
file something like this:
# note that your page /some/other/page/index.html will be served
# from http://foo.bar.com:8080/some/other/page/index.html
# not http://foo.bar.com:8080/page/index.html
foreach method [list GET HEAD POST] {
ns_register_proxy $method /some/other/page/index.html \
http://foo.bar.com:8080
}
ns_register_proxy syntax is the same as ns_register_proc
I you want even more stuff like this, serach for my posts to the list.
Some time ago I had sent to the list a proposal to add such
functionality to AOLserver core (along with my single server virtual
host extention patch and test cases), but it was ignored by a core team.
Recently I've put nsvhr in production enviroment and there are problems
with pages served from proxied Apache. I've never seen any problem with
proxing AOLserver though. So be carefull, because I'm not sure if nsvhr
is really well tested module. Maybe you should use Apache with its
ProxyPass directive as frontend server and AOLserver as backend or even
something like squid or ?ponds? which was also discussed on this list.

Re: [AOLSERVER] Topic gripe .. was Re: [AOLSERVER] virtual hosting options and a fantasy ....
Just an FYI - the work is nearly complete on an JK2 family module for AOLserver 4.0. Obe possible option in nsjk2 is to start Tomcat in-process and be able to evaluate Tcl code from Java (e.g., can have an .adp include in a .jsp). The module supports multiple virtual servers in AOLserver 4.0. Regarding some of the points I saw in another thread: -- having a JVM instance per-thread: serious application server with many classes/servlets loaded will have prohibitive memory requirements. -- small application server vs. full-featured one, like Tomcat -- the latter has much better chance to adhere to standards should you need portability in future, or decide to couple servlet-capable Web server with Java application server.

If the J2EE server has a built in http server, that can be much more (and is!) efficient then using a plugin. When you do not want to use a web interface, don't use it and it sits idle, nothing lost. That is not to say that I don't think a JK2 module for AOLserver is not a good idea, it is a great idea. More and more enterprise back-ends will be using J2EE and if AOLserver can interface with those, that is a greta thing. Alex I.

Edward Wilson said: Why would the AOL team think so selfishly by removing virtual hosting? Do they not care that others rely on their server? You are quite passionate about this, aren't you? ;-) Although there was virtual serving in 2.3, it was not hostname based. Personaly, I find that instead of putting extra directives in one config file, moving them to different config files and having some more lines in my start-up scripts not really a big deal and certainly not something that significantly breaks moving code from 2.3 to 3.0. The trade off is worth it considering how much more lean and mean 3+ is! As an added bonus you get a completely seperate environment! I don't find AOL selfish at all for making any changes, they build a kick-ass server for themselves and share it with the world, thank you very much. They will not make application breaking changes because they are their own major client and don't want to break their own apps. Looking at the track record, maintaining almost 100% code compatibility from 1995 to 2003 (dispite architecture changes) is unheard of in the world of web application servers! Bas.

You may want to investigate alternatives to getting free software from a public server or cvs. Some alternatives include: 1. purchasing a server - but then, you still don't have the certainty that you require I guess. 2. purchasing support - then at least you could work with someone to reimplement features that are missing 3. freeze at a particular version of the software that meets your needs, and just live with bugs and without new features, or even attempt to 'back port' fixes and features to your frozen version yourself. 4. write your own server. 3 of the 4 can give you the assurances you need. -- Tcl - The glue of a new generation.

Edward Wilson wrote: Why would the AOL team think so selfishly by removing virtual hosting? Do they not care that others rely on their server? Nothing was lost in removing virtual hosting, except the difficulty of mantaining a single config file for all those hosts. Since each server takes up as much memory running separately as when combined, resources are not saved. This is very different from Apache which could easily run thousands of virtual hosts without increasing memory useage (since is spawned a new process for each request anyway). With the style of virtual hosting in the pre 3.0 series, any change to a virtual server would require a restart of the entire process, bringing down every virtual host in the process. Since each virtual server was initialized separately, the time to restart was proportional to the number of virtual servers. I don't know what the current situation is with the new implimentation, but if it is the same, I can't see why it would be useful. I believe the config file problems are greatly reduced. In the mean time several users, including myself, developed virtual hosting using registered filters. This proved to be very efficient, even when written in tcl. --Tom Jackson I.

Re: [AOLSERVER] virtual hosting options and a fantasy ....
I get the feeling this thread might run for a while... -Original Message- From: AOLserver Discussion [mailto:[EMAIL PROTECTED] Behalf Sent: Tuesday, March 04, 2003 7:43 PM Tomasz, et. al. I can think of a dozen different ways (maybe not soo many) to implement name based virtual hosting, and the choice really comes down to who you are and what you are trying to do. Yep, and I personally think that trying to get one 'product'/'application' (whatever you want to call it) to do everything is starting to tread on dangerous ground: The danger being that an application that was once very good a few things, gains the capability to do lots of other whizzy things but ends up doing none of them particularly well. I personally think that where possible it is best split functionality out by server (or even machine) to allow them to be tuned to the n'th degree (both at a code and configuration level) for the specific purpose they are built for. This also reduces the need for some of those crazy internal interdependencies you hit which makes maintaining these systems a headache. However separate processes clearly tend not to be as tightly integrated as a single one - so there are of course, pros and cons of each. The solution you go for is likely to be based on which of the various considerations you mention is most important to you, and its unlikely (in practice anyway) that they are all going to be of equal priority. Also, don't forget that there are hardware appliances out there that perform many of the functions you are discussing - it all depends to some extent on how big (or rather full) you wallet is, So: (all, forgive me if I'm stating the obvious!) Maybe you have and or want 1. One machine and many completely different websites run for completely different users (requires high security isolation from server instance to another) As you suggest separate virtual machines gives you the isolation (security often comes down to good practice and the detail of configuration) 2. One machine and machine completely different websites run for the same user (security not as important) AOLserver will do this with either name based virtual hosting or IP based virtual hosting 3. One machine and many different websites but not completely independent websites? (may want to share code, db, and some images) Again AOLserver will do this for you (well certainly v4 from what I can tell), with various ways to share code, db and files 4. Variations of 1-3 above but where you want high uptime for all servers and don't want one coming down to affect others? If you are serious about high uptime you want more than one machine to reduce the effect of hardware failure. To ensure that a site failing has the least effect separate processes for each site seems to be a solution, but that doesn't stop for example one of those processes turning rogue and consuming all the resources, rending the other processes unusable According to the hype AOLserver is fast, efficient and reliable - I've yet to put it into production so I can't yet verify whether this is the case or not. ;-) 5. You're need to add/remove sites at runtime. I don't think AOLserver (4) allows you to do this out of the box, but there are C,Tcl and hybrid modules available that should. 6. You want high uptime and so you have more than one machine at maybe more than one geographical location and youwant all these to be running the same dynamic website. Again, there's more than one way to skin a cat. EdgeCaching, reverse proxy caching, source based traffic routing etc. etc. 7. You want a reverse proxy to stitch together many independent technologies (tomcat, jboss, aolserver,apache, zeus/nuke,snmp management, bob's special little webserver) that each provide an html stream in their own process all under the same port 80 url) (nsvhr does this well.) I think there's room in this area for a whole suite of products to be born - I've got a couple of ideas for one or two of them - just need the time and the money to turn them into reality Okay, a baker's 1/2 dozen of reasons for virtual hosting. There's probably at least as many that you haven't though of (don't get me wrong not a criticism at all - but someone out there is bound to be putting pretty much every permutation into practice) Unless you need to share db or session information, or unless you have very small machines, I don't see AOLserver as the best way to provide most of these solutions. Though I've tried hard in the past to make it do so You have the upper hand on me here as I don't have the practical experience of AOLserver that you do, but if it performs as well as is claimed then, as you say, with the help of one or two well chosen friends it ought to be able to do the job most admirably. The question is do you really want to try and get AOLserver to do it all by itself (without external help)? But between SQUID and Apache as
Re: [AOLSERVER] Virtual Hosting by Name not IP.
You can do this with AOLserver v4 as it comes (out of the box) - look in the list archive for the example config file I sent a couple of days ago, which has an example of this. If you are using v3.x then there are various C, Tcl or C/Tcl add-on modules that will let you do this.

Thank you, not specifying the port parameter in nsunix did the trick.

Jerry,
Please show the nsvhr and nsunix config parts of all three config files.
Your nsunix config should look like this in the slave server files:
ns_section ns/server/${server}/module/nsunix
ns_param hostname www.mydomain.com
ns_param socketfile mydomian.nsunix
Do not set the port param for nsunix. If you do it will show the port
number.

Hello,
I just installed virtual hosting on my machine (using Aolserver3.3ad13)
I used Jerry's nsvhr/nsunix config found on his site.
I have 3 sites :
master.mydomain.com:8080
sub1.mydomain.com:8081
sub2.mydomain.com:8082
Redirection works well, but the URL in the browser shows the actual port of
eiher site (8081 or 8082) instead of 8080.
i.e: query ; http://sub1.mydomain.com:8080/index.html
response : http://sub1.mydomain.com:8081/index.html
It bother me, because when I go live, I will put master.mydomain.com on
port 80, and I dont want to see any port in the browser URL for my subsite.
Is it possible to :
query : http://sub1.mydomain.com:8080/index.html
and have a response : http://sub1.mydomain.com:8080/index.html
(same port showing, wich means no port showing when on port 80)
Thx
Re: [AOLSERVER] Virtual hosting using nsvhr : port number appears inURL
I think Jim is right that a tcl based solution will most likely prove fast enough. There are a number of programming decisions you need to make if you choose his path for a roll-your-own vhost server. I have several tcl only solutions, one that is a proxy and one that uses url mapping. The mapper is at http://zmbh.com/vat/ and the proxy is at http://zmbh.com/tclvhr/ I don't know if either solve your particular problem, but they are written in tcl and easy to configure or adapt to your situation. Bug me if you have questions. --Tom Jackson

Re: [AOLSERVER] Virtual Hosting in AOLserver
Thanks. I do these to test the new code in machine which is running old server. Now I can test it while original server is running. :) Sorry for my poor english and thanks again. - Original Message - From: Brian Fenton [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, May 13, 2002 7:18 PM Subject: Re: [AOLSERVER] Virtual Hosting in AOLserver Here's what I do when I want another AOLserver on a different port. Make a copy of the config file and edit it and change the values of Datasource (SID), User Password (if you're using a database), ServerLog, AuxConfigDir, PageRoot, Library, Port, Hostname and Address. That's based on a quick glance - there may be more you need to change. Oh yes, also change all the ns_section ns/server/servername lines by replacing servername with something else. You need to make a copy of all your tcl programs too. So for a quick result, take a copy of an existing website and put it where ever your PageRoot parameter above is set to. This will give you a working site very quickly. If, like me, you use up and down scripts, make new ones of those too and tell the up script to use the new config file. I'm assuming here you don't want proper Virtual Hosting. If you do want that there are a few options you can try - these should really be listed on aolserver.com somewhere, but they're not. :-) The one we use is Jerry Asher's - see http://www.theashergroup.com/tag/articles/nsvhr/virtual-hosting-howto.adp It works very well for us.
