Frontend caching to multiple sites
Hi all, First let me congratulate the people involved in Varnish, great software!!! I've looked around the the mailing list but was unable to find an answer to my question. I want to set up varnish as a reverse proxy/cache to multiple customer sites. As in, I have 10 different customers, each with its own web site (domains) with their own necessities, compression, cookie, authentication, etc; each customer is a different setup from the other, so I thought "OK! Let's use a different VCL for each customer and all will be fine". Bear with me here, I've just started playing with varnish, but it seems that I can't create a different VCL file for each customer and load it in varnish (vcl.use ...) as varnish will stop responding for the previous site and start responding only to the new one (active configuration). Meaning, the content that is served is only the content from the new site, even if using the correct domain. How can I go about setting this up? I'm using Varnish 2.0.1, just downloaded and compiled it today. I really aprecciate all the help you can give!

Re: Frontend caching to multiple sites
Hi Espen,
Thanks for the answer!
Is there a way to accomplish this using different VCLs?
I ask it because I'm trying to figure out a way to make it automatic. As in
if I have a new customer, I'd just fill out a form (with the customer
details like domain name, backend server, other configuration) and a little
system working under the hood would generate the VCL file, send it to the
varnish server and load it.
If I use one VCL file for everybody, how do I reload this VCL when I need to
change it? Is it necessary to reload varnish? Would it present downtime?
Thanks!!

TCP_HIT header
Hi guys, Is there a variable that I can print on the response header that will give me the cache lookup result such as TCP_HIT or TCP_MISS? Thanks!! Alecs ___ varnish-misc mailing list varnish-misc@projects.linpro.no http://projects.linpro.no/mailman/listinfo/varnish-misc
Re: TCP_HIT header
Hi Per,
Thanks for the reply!
The issue here is not how to add the header, that is OK, I can do it just
fine (even added the Foo: bar header just for the fun of it!). The problem
is WHAT variable I can use that contains that information (MISS or HIT).
Is there more documentation on the variables available than what is in
vcl(7)?
Or anywhere else for that matter.
Thanks,
Alecs

Re: TCP_HIT header
Hi Per,
Here's what I got:
-
vcl.load test /usr/local/etc/varnish/configs/test.vcl
106 267
*Variable 'obj.http.X-Cache' not accessible in method 'vcl_miss'.*
At: (/usr/local/etc/varnish/configs/test.vcl Line 62 Pos 13)
set obj.http.X-Cache = "TCP_MISS from " server.ip;

VCL compilation failed

It works just fine for vcl_hit though.
Any ideas?

Re: Varnish Error 503 Service Unavailable
Hi there! I have the exact same problem, and it comes and goes as it pleases.. I'm testing varnish with different backends (different customers sites in the same instance) and every once in a while it locks up at the same place (the X-Forwarded-For header on varnishlog) for any site. Not the others though, as they are accessible through varnish just fine. And after a while of working the cache the site that locks up comes back to life. This is what varnishlog shows just before the 503 error: Request: 9 SessionOpen c MY_IP_ADDRESS 56186 VARNISH_SERVER_IP:80 9 ReqStart c MY_IP_ADDRESS 56186 444163595 9 RxRequestc GET 9 RxURLc / 9 RxProtocol c HTTP/1.1 9 RxHeader c Host: BACKEND_HOSTNAME 9 RxHeader c User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en; rv: 1.9.0.3) Gecko/2008101315 Ubuntu/8.10 (intrepid) Firefox/3.0.3 9 RxHeader c Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 9 RxHeader c Accept-Language: q=0.8,en-us;q=0.5,en;q=0.3 9 RxHeader c Accept-Encoding: gzip,deflate 9 RxHeader c Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 9 RxHeader c Keep-Alive: 300 9 RxHeader c Connection: keep-alive 9 VCL_call c recv 9 VCL_return c lookup 9 VCL_call c hash 9 VCL_return c hash 9 VCL_call c miss 9 VCL_return c fetch 9 Backend c 17 BACKEND_NAME BACKEND_NAME 17 TxRequest- GET 17 TxURL- / 17 TxProtocol - HTTP/1.1 17 TxHeader - Host: BACKEND_HOSTNAME 17 TxHeader - User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en; rv: 1.9.0.3) Gecko/2008101315 Ubuntu/8.10 (intrepid) Firefox/3.0.3 17 TxHeader - Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 17 TxHeader - Accept-Language: q=0.8,en-us;q=0.5,en;q=0.3 17 TxHeader - Accept-Encoding: gzip,deflate 17 TxHeader - Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 17 TxHeader - X-Varnish: 444163595 17 TxHeader - X-Forwarded-For: MY_IP_ADDRESS ===> Long waiting time (sorry, didn't really time it, but it's like 5 minutes) Response: 17 BackendClose - BACKEND_NAME 9 VCL_call c error 9 VCL_return c deliver 9 Length c 452 9 VCL_call c deliver 9 VCL_return c deliver 9 TxProtocol c HTTP/1.1 9 TxStatus c 503 9 TxResponse c Service Unavailable 9 TxHeader c Server: Varnish 9 TxHeader c Retry-After: 0 9 TxHeader c Content-Type: text/html; charset=utf-8 9 TxHeader c Content-Length: 452 9 TxHeader c Date: Tue, 11 Nov 2008 11:49:00 GMT 9 TxHeader c X-Varnish: 444163595 9 TxHeader c Age: 945 9 TxHeader c Via: 1.1 varnish 9 TxHeader c Connection: close 9 ReqEnd c 444163595 1226403195.496297359 1226404140.571825743 0.000217438 945.075489759 0.38624 9 SessionClose c error 9 StatSess c MY_IP_ADDRESS 56186 945 1 1 0 0 0 236 452 0 StatAddr - MY_IP_ADDRESS 0 427594 323 1326 0 0 548 435744 9005255 9 SessionOpen c MY_IP_ADDRESS 44754 VARNISH_SERVER_IP:80 9 ReqStart c MY_IP_ADDRESS 44754 444163596 9 RxRequestc GET 9 RxURLc /favicon.ico 9 RxProtocol c HTTP/1.1 9 RxHeader c Host: BACKEND_HOSTNAME 9 RxHeader c User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en; rv: 1.9.0.3) Gecko/2008101315 Ubuntu/8.10 (intrepid) Firefox/3.0.3 9 RxHeader c Accept: image/png,image/*;q=0.8,*/*;q=0.5 9 RxHeader c Accept-Language: q=0.8,en-us;q=0.5,en;q=0.3 9 RxHeader c Accept-Encoding: gzip,deflate 9 RxHeader c Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 9 RxHeader c Keep-Alive: 300 9 RxHeader c Connection: keep-alive 9 VCL_call c recv 9 VCL_return c lookup 9 VCL_call c hash 9 VCL_return c hash 9 VCL_call c miss 9 VCL_return c fetch 9 Backend c 14 BACKEND_NAME BACKEND_NAME 14 TxRequest- GET 14 TxURL- /favicon.ico 14 TxProtocol - HTTP/1.1 14 TxHeader - Host: BACKEND_HOSTNAME 14 TxHeader - User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en; rv: 1.9.0.3) Gecko/2008101315 Ubuntu/8.10 (intrepid) Firefox/3.0.3 14 TxHeader - Accept: image/png,image/*;q=0.8,*/*;q=0.5 14 TxHeader - Accept-Language: q=0.8,en-us;q=0.5,en;q=0.3 14 TxHeader - Accept-Encoding: gzip,deflate 14 TxHeader - Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.7 14 TxHeader - X-Varnish: 444163596 14 TxHeader - X-Forwarded-For: MY_IP_ADDRESS Any one else seeing this?

Variable for backend host
Hi All! Is there any way to access the backend host name in VCL? What about obj.ttl? What I'd like to do is place that information in a header, and maybe log it. While we're at it, is there a listing of the available variables to be used in VCL? Thanks!

Hi there! Is there any way to tweak the varnishncsa log? For instance, if I wanted to log to a file a specific header set by varnish itself. Or a hedaer sent by the backend. Thanks!

What to do when the backend sends no caching information?
Hi All, In testing varnish in different situations, I came accross a backend that sends no caching information in its responses, no Expires, cache-control or anything. Ok, I thought, I'll just set the TTL on that object (namely an html page) in VCL. Well, turns out varnish may be setting the ttl all right (I do it in vcl_fetch, but frankly there really is no way to see if it is set correctly or not! or is there?) but the page always gets a PASS, never a HIT. Age: is set to 0 by varnish. Thanks for all the help! Alecs ___ varnish-misc mailing list varnish-misc@projects.linpro.no http://projects.linpro.no/mailman/listinfo/varnish-misc

Re: What to do when the backend sends no caching information?
Hi Per, I'm actually using the cookies in the cache (using the information provided on the website -- set req.hash += req.http.cookie;) and it works just fine! One thing that the backend does is vary on user-agent, not only content-encoding (I've removed the UA vary on the response, though). So looking into varnishlog I can see the pass, even after the hash is shown correctly. Any pointers? THanks!

Weird log entries
Hi guys, I was wondering if any of you has seen the following log entries when using varnishncsa: 127.0.0.1 - - [00/Jan/1900:00:00:00 +] "(null) (null) (null)" (null) - "-" "-" Those are coupled with: 127.0.0.1 - - [09/Feb/2009:19:39:46 +] "(null) (null) (null)" 200 39678 "-" "-" I can see an object in the page that has that size (image) -- through firebug, but the object didn't load into the browser until I hit reload. And there are also many entries like the following: 127.0.0.1 - - [09/Feb/2009:19:39:52 +] "GET http://www.example.com/img/mod.gif HTTP/1.1" 200 951 " http://www.example.com/style.css"; "Mozilla/5.0 (X11; U; Linux x86_64; en; rv:1.9.0.5) Gecko/2008121623 Ubuntu/8.10 (intrepid) Firefox/3.0.5" These entries are from communication with the backend server I expected it to show the backend name instead of 127.0.0.1.

Re: Weird log entries
So, after a while digging through other stuff I realized what the "(null)" entries are. They are cache misses. For (apparently) every miss there's an entry on varnishncsa for that miss, and it's logged as a bunch of nulls. I haven't figured out what the other entries are though. I still see some entries (not as many as the null ones) with the date field set to "[00/Jan/1900:00:00:00 +]", with all the other information valid (URL, Referer, BackendName, etc..) except for the object size, which is set to "(null)" and ther server response code (also "(null)"). There are also entries that the only field set is the server response (200 or 404 -- these have the date field set correctly) and some entries with the host (or where the backend name should go) set to 127.0.0.1 and the other fields set correctly. One thing though, in none of the entries (correct, broken or plain weird) the object size is set, all I see are "-", except for one entry that had it set (strangely enough, favicon.ico!) and even then, only once. If anybody else has seen this stuff or know anything that might help explain, I'd greatly appreciate some help. I can also send you any information you might deem necessary in order to figure this stuff out. This is the varnish package for debian (2.0.3-2_amd64) all with HTTP/1.1 requests. Thanks!

varnishncsa backend logging
Hey guys! I've just run into the most peculiar problem.. Actually, I just now realized this happened.. Logging the requests to the backend with varnishncsa, generates a log file that is missing the object lenght field. Actually not missing, but it always comes out as "-". This does not happen to client requests log, just backend. I thought that it could be something related to the VCL, so I tested with an empty vcl (just the backend declarations) and the problem persists. Looking into varnishlog, it shows the object being fetched from the backend alright, but all the content-lenght headers are not there (nor in RxHeader or ObjHeader), yet varnish knows the size of the object and delivers it to the client with the correct lenght header. I would think that varnish does not recompute the size of the object in order to deliver it to the client.. So the question is: what is happening? Running 2.0.4 in debian lenny amd64. If anyone can confirm that this is the case in their installation and maybe provide it would be great! Thanks!
