mod_jk and 304
I have tomcat running behind apache http server 2.0 using mod_jk. I have noticed that this causes any response to request for files in tomcat that return a 304 status code, to also have a 20 byte message body attached to the response. This causes our load balancer to think this is an error as according to rfc2616 304s must NOT contain any message body.
If I directly go to file in docroot of the webserver, there is no problem, but if files are requested from tomcat via mod_jk, it is causing issues.
Anyone faced this issue?
I am using tomcat 5.5.16, with apache 2.0.59 on suse linux 9.
Thanks

Yes I tested on newer version as well, but could not reproduce it there. The extra bytes are not content and they are always the same regardless of what resource is requested. How do I find the mod_jk version? It came with the suse distribution. I tried debug logging, but that didn't spit the version.

I'm not seeing that problem on my system, but I'm running newer
versions (httpd 2.2.9 and Tomcat 6.0.18). I do recall seeing some
strange 304 responses with 2.0 & 5.5, but it was a while ago and I
don't remember if the problem was extra bytes in the response.
What version of mod_jk are you using? I'm using 1.2.26. If mod_jk is
old you could try updating it. (I know it's a pain to update the whole
web server just to test, but upgrading just mod_jk is easier.)
What are the extra 20 bytes? Are they an actual message body or garbage?

I have mod_deflate enabled on apache for css, js files etc. I tried getting a css file directly from apache httpd and it didn't have any problems, but if the css and js files are in tomcat, apache always seem to append some bytes in the message body when there is a 304 response.

Some additional info I found on this:
It seems that combination of mod_deflate and mod_jk is causing the issue. I have mod_deflate enabled on apache for css, js files etc. I tried getting a css file directly from apache httpd and it didn't have any problems, but if the css and js files are in tomcat, apache always seem to append some bytes in the message body when there is a 304 response.
