Reverse squid proxy does not show always tomcat webpage
-
Hi,
I use wonna use reverse squid proxy before our Novell Vibe server.
Vibe is a Tomcat Application that uses internal 8080 and 8443.The config now is:
vibe.domain.ext –> 80 --> squid --> 8080 --> Vibe server
vibe.domain.ext --> 443 --> squid --> 8443 --> Vibe serverWith the ssl config i use an cert on the squid en one on Vibe.
I made two webservers an two mappings in the config.The problem is that the Vibe site does not always show up. Its not stable. Its hanging or very very slow.
I also use Groupwise and that goes right or just a simple site. I also set the firewall open, but no resultsWho can help me with this problem or what do i wrong. Is there a log that i can read except the realtime log?
Pleas help!

check squid access.log and cache.log

Thanks for your reply.
In the access log the http site does get logged correct one time.
The second time nothing is logged. When i call the https one line get logged with a time out i gues.1340818529.227 3 82.168.159.164 TCP_MISS/302 291 GET http://vibe.domain.ext/ - FIRST_UP_PARENT/HOST1 -

That is correct. I have set it on port 85.
The 4 lines are the same external ip address but FD differents.
What does FD means?Accepting accelerated HTTP connections at xx.xx.xx.xx:80, FD 21.

When i use only the http reverse mode the Novell Vibe site is stable reachable.
As soon as i also use the https reverse mode the connection wil become unstable. This is also when i only use the https reverse mode. The site wil become unstable to connect.
Do you have an other idea that i can check?
-
Has anyone else an idea? :'(

Solved! With the new package marcelloc made and the right regex its works good. Thanx! :D

Thanks for the feedback klokslag. Did it worked with both protocols(http and https)?
att,
Marcello Coutinho -
It works with both protocols. I'm trying now an second url to work with https. But haven't succeeded yet. Because it still redirect to THE default/first site. Http works fine.
Do you have an idea.
-
Do you have an idea.
Do you see any erros/ missing config on squid.conf file?
Just a note that may help:
I'm finishing a new package gui version for apache+mod_security, I think this new package will do a much better job on http/https reverse proxy.
I've tried to finish it last week but there is still missing features to include.att,
Marcello Coutinho -
I do not see any errors in the cache logn the or squid.conf.
I think it has to do with the default site with the https protocol.
When i put there the second url in it, that url works too but not the first.But if you think apche+mod_security will work better? I will wait when you finished it and will test it.
Let me now when your finished it.Regards.
