I'm compiling mod_perl into apache 1.3.xx (19 i think) and all the mod_perl make, make install goes ok. APACI ./configure is fine too, but when i make apache, I get about a page of complaints about mod_perl, mostly of the format "Undefined reference to mod_perl_some_function_name in mod_perl.c" and it won't make. make and make test on mod_perl both complained about libwww missing, but all the install notes said this isn't absolutely required. without the activate-module=src/modules/perl/mod_perl.c apache completed make install with no probs (well it runs anyway) any ideas?
Re: Apache::ASP rules [was: Sorry men]
Horror stories? On a live site when a static page is being accessed NT can lock the page and not unlock it even when you've stopped the internet service - handy when you've got someone shouting at you to change a mistake. If you change the default (eg index.htm) page in a directory to a dynamic one eg index.asp, IIS will show an older cached version of the page if you view the page using just the directory name in the URL and th new version if you call it explicitly. Oh - and try looking for the error log on IIS. Also take a look at the IIS version of W3C logs - they're full of corrupt chunks of HTML (?? - this makes them near impossible to process with PERL on NT - I had a site once where we zipped up the logs and sent them to a Linux machine for processing) Much touted as an advantage of IIS is the Site Server add-on. This is even worse than IIS. Index Server is the worst piece of software I have ever worked with. If you search for two words and have a document that contains 14 occurences of one word and 1 of another it will rank higher than one with 7 of each. If you try to catalogue a collection with over about 20,000 pages it can't push the collection to other servers so you have to set up indexing on all your servers which is something Microsoft tell you not to do because Indexing brings your server to a halt. The LDAP service is a joke. It stops and starts for a hobby and relies on you first setting NT group permissions on all the folders you want to apply it to (??). Try ringing MS for LDAP support and you will get to speak to a lot of very confused people. The last time I tried I waited a week and then got back a list of people offering IIS training in my area. And have you ever tried sending mail from an NT server? I tried to use the Membership stuff to send a weekly newsletter from a $40,000 Compaq server and worked out it was going to run into next week's letter. Roll on Linux running on an old Pentium II. And have you ever tried dialling in remotely? And my favourite - MS make a great dea about how much of the Linux stuff is freeware or open source. If you get a runaway process on NT and you can't kill it - ring up MS Support and they'll recommend installing a shareware utility called kill. Sure I use shareware to do lots of stuff - but to kill a process on a mission critical server?? Still it's not all bad...I like the Unix compatibility pack and the GUI gets more like the Mac every release. I feel better now.

MS Is there any benefit of mod_proxy over a real proxy front end like "Oops"? Not being familiar with "Oops", I can say that I use mod_proxy as the front end so that I can do virtual hosting. Doing this with Squid is not so straight-forward (meaning it requires me to spend lots of time learning something else to maintain.) We use squid as the front end proxy for about 180 domains and it works well. It catches about 50 "stupid redirect" domains, ones that bounce to a subdirectory of a larger site. We reckon at least 50% of all traffic is cached, which is to be expected as our sites are heavily SSI driven and therefore regular html just doesn't cache and nor should it. Squid's OK and a lot better than it used to be. If we were running on less hardware (currently 3 tier: proxy, 2xmod_perl servers, database), then I'd think hard about using a single, modular apache build and two instances of apache. I'm currently arguing about this very thing with my BOFH - I think we should have, effectively, an SSI apache and a mod_perl apache, he's going with the KISS principle.

I'm sorry, I was away and didn't have a chance to answer mod_perl emails
yet. I saw your post at the list.
It seems that you and me have the same system. Mine is linux RH6.1
apache1.13 mod_perl1.23 perl5.005_03. And it works Ok.
Your problem has nothing to do with Apache::VMonitor, since it relies on
Apache::Util to work. You should post a proper bug report to the list. By
proper I mean asking for help with Apache::Util and not Apache::VMonitor,
so the right people will look into it.
You should try this script:
my $r = Apache-request;
$r-send_http_header("text/html");
use Apache::Util ();
print Apache::Util::escape_html("code");
If this doesn't produce "code" and produces the same errors, you have
some problem with Apache::Util. Did 'make test' pass Ok when you have
installed mod_perl?

Can round-robin DNS be counted on to send people back to the same server over the life of a given session? They can all go through the proxy, the savings is that the proxy will buffer down the slow internet pipes that clients have, freeing up the modperl httpd for other things. About load balancing, we are running the StateDir to a non caching NFS mount point to a NetApp cluster. There is a problem with NFS locking, and Apache::ASP can't ensure data integrety over the network, even if patched up to use NFS locking. Seem like there might be Linux NFS locking unresolved issues, that people see with MySQL too. The upshot is that in this environment, it helps to use SDBM_File, the default, not DB_File, since DB_File gets corrupted, whereas SDBM_File may just not save some data if there are too many concurrent hits, but Apache::ASP will repair the parts that are necessary, as this is all really concerning a central db that it keeps. Further, I have recently done some work in my dev v.19 so that there will be fewer problems with the Session_OnEnd event, with the fix being to have one process on one web server being responsible for session management at any one time, so there are not conflicts which there would otherwise be. With sharing state files to an NFS share, the sessions can move from server to server even if one server goes offline, which you won't find with solutions that have clients stay on a server saving session data locally in RAM or disk. On my sites I use a central database for storing the session objects, and all of the https servers access this central resource. Obviously if it goes down, everything is toast, but the same can be said of the database that stores all of the customer information, etc. -jwb
error in Apache::Util
Hi!
I'm running mod_perl 1.23/apache 1.3.12/perl 5.005_03 on Mandrake 7.
mod_perl seems to be up and running and things are working well.
However, I add:
Location /test
SetHandler perl-script
PerlHandler My::Test
/Location
and Test.pm looks like:
sub handler {
my $r = shift;
$r-send_http_header("text/html");
use Apache::Util ();
print Apache::Util::escape_html("code");
}
When I go to /test I get internal server error, and this in the logs:
[Fri Apr 28 12:59:57 2000] [error] Can't locate loadable object for

mod_perl Win32 binary
Hi, I've placed at ftp://theoryx5.uwinnipeg.ca/pub/other/ (linked to from http://perl.apache.org/) a self-extracting archive (perl-win32-bin-0.6.exe) containing Win32 binaries of Perl-5.6.0, mod_perl-1.23, Apache_1.3.12, and mod_ssl-2.6.3-1.3.12. Perl was compiled without fork emulation, and consequently this binary is not compatible with ActiveState's Perl. As well as some popular non-core modules such as libwww, Tk, and GD, this package also contains DBI and drivers such as CSV, ODBC, mysql, and msql, as well as HTML::Embperl-1.3b3, HTML::EP, HTML::Mason, and others. Included are installation instructions - please let me know of any problems. best regards, randy kobes

What's next for Apache::Session
The next version of Apache::Session is almost ready. This version is dubbed 1.50 because of it's significant-but-not-outrageous changes. The changes from 1.03 are: 1) New backing stores can stash data in Berkeley DB via the BerkeleyDB module, or any dbm format via AnyDBM_File. 2) The ID generator and the data serializer are no longer hard-wired into the Session superclass. They are pluggable and interchangeable in the same way that the backing store and locking manager are in 1.03. This was done mainly for people who implement non-jwb session ID policies and to increase compatibility with non-mysql databases. Users of postgres can now create ASCII serialized sessions by using the Base64 serializer. FreezeThaw serialization is also supported. 3) The new interface class Apache::Session::Flex allows the runtime specification of the backing store, lock manager, serializer, and ID generator. This was by popular demand, and should benefit rapid development as well as other systems like Embperl and ASP. 4) The DBI interface class has been modified to accept an already-open DBI handler as an argument. 5) New interface classes have been added for Apache::Session::Postgres, ::Sybase, and ::Oracle. These are special cases of ::Flex. That is all. I'm working on it this weekend if anyone has any more suggestions. Regards, Jeffrey

I was under the impression that Sleepycat is a much better solution for embedding into an application, where all data is kept in memory. I wouldn't think .db files could come close to a caching DBMS like MySQL, unless the .db file is on a caching filesystem. Another plus for using MySQL to store sessions is that version 3.23 (alpha) has entirely in-memory heap tables. This is a perfect fit for session data, since sessions typically last a very short time, and one can assume the database restart to session turnover ratio is very low. -Adi

Re: modproxy:modperl ratios...
A few lessons on this arena: 1) Move your pictures to another server *even if you're using a proxy* Search back in the archives for my previous post on this topic. 2) If you use mod_proxy you can give it the same web root and have it serve some static objects itself instead of having to cache them. But 1) is even better than doing this. Sometimes you might not have a choice, such as with java applets. 3) mod_proxy is poorly designed and poorly implemented. The main deficiency is that each process is responsible for opening and maintaining its connection to the backend. This defeats keep-alives completely and forces a lot of overhead in the kernel and the servers. There's a much better design that involves creating a fixed number of sockets and treating that as a shared pool. In that design the backend can have a long keep-alive timeout and maintain persistent connections to the front-end. Despite these concerns I've been using mod_proxy myself and it does work. I'm planning to change to mod_backhand though which implements 3) but it's new code. -- greg
Re: modproxy:modperl ratios...
Yep all these things are true. Well, the part about being poorly designed is wrong, it just was designed well, then hacked to death :-), I guess I'm splitting hairs, but the essential design is easy to follow. I picked up the entire module in a just a few hours. (I just think it isn't fair to the original designer to say that :-) Anyhow... I've heard the keepalives are getting fixed, but I haven't seen any code yet. Theres also other stuff in the mix that I think you guys will see start to show up in say 1-2 months that will make mod_proxy..., or whatever mod_proxy becomes into a mean lean webserving proxy machine! Seriously though... with all the stuff that's happening with this module, I think you guys will be really happy with the results. One thing to note that might be slightly sad..., I've heard it might be breaking from apache into a seperate program. Become a seperate ASF project. This is something that's being tossed around, but likely it will use all the same directives that folks are used too etc. Oh well, I don't know if that will happen, but admittedly it makes sense. It just seems theres so much that could be done with it for 90% of the platforms, but 100% just won't make it in. So it's either split with apache and have mind numbing performance, or have something mediocre (like we have now). Also if we split, it's going to be a lot lighter weight than it already is. In short... this module is in for lots of cool stuff. And I'm speaking of lots of developers working on it. Four that I know of for sure, two of which have already done a huge body of work on this module. Thanks, Shane.

But 1) is even better than doing this. Sometimes you might not have a choice, such as with java applets. 3) mod_proxy is poorly designed and poorly implemented. The main deficiency is that each process is responsible for opening and maintaining its connection to the backend. This defeats keep-alives completely and forces a lot of overhead in the kernel and the servers. There's a much better design that involves creating a fixed number of sockets and treating that as a shared pool. In that design the backend can have a long keep-alive timeout and maintain persistent connections to the front-end. Despite these concerns I've been using mod_proxy myself and it does work. I'm planning to change to mod_backhand though which implements 3) but it's new code. -- greg
