Question about mod_ajp and mod_jk ProxyPassReverse

Guys,

We are switching out mod_ajp for mod_jk and have ran into a wall with Prox=
yPass and ProxyPassReverse.

With mod_ajp we have this setting



BalancerMember ajp://tomcat05:8009 smax=3D20 min=3D0 max=3D10 loadfactor=
=3D1 flushpackets=3Don route=3Dnode1
BalancerMember ajp://tomcat06:8009 smax=3D20 min=3D0 max=3D10 loadfactor=
=3D1 flushpackets=3Don route=3Dnode1



ProxyPass /travelchannel balancer://potapp/travelchannel/
ProxyPassReverse /travelchannel balancer://potapp/travelchannel/

ProxyPass /travel balancer://potapp/travel/
ProxyPassReverse /travel balancer://potapp/travel/

ProxyPass /AppConsole balancer://potapp/AppConsole/
ProxyPassReverse /AppConsole balancer://potapp/AppConsole/


When we try to use these setting that work with mod_ajp, we get a 404 with =
mod_jk. I have no clue. Do I need to do something different with ProxyPass/=
ProxyPassReverse? I been seaching the net with no luck.

Most people ditch mod_jk for mod_proxy_ajp.
Care to elaborate as to why mod_proxy_ajp isn't working for you?

You need to make sure that your URLs are balanced - if the URL you are
passing ends in a slash, then the URL you are passing it to must also, and
vice versa.

Eg,

ProxyPass /travelchannel/ balancer://potapp/travelchannel/
ProxyPassReverse /travelchannel/ balancer://potapp/travelchannel/

Cheers

Tom

RE: Question about mod_ajp and mod_jk ProxyPassReverse

Because we are running productions, as stated on the Apache site in BOLD le=
tters, mod_ajp is not for production use. We see our jboss down with it.

RE: Question about mod_ajp and mod_jk ProxyPassReverse

I agree with Chuck here - would definitely NOT use mod_proxy_ajp in
production and would ALWAYS use mod_jk

Back to the original question - have a look at
http://tomcat.apache.org/connectors-doc/reference/printer/ap ache.html - in
particular the "JkOptions +ForwardURICompat " part.

I think this will allow you to do mod_rewrite in combination with mod_jk -
I must say I have never done this myself but it should be possible...

Danny

I see a few references to mod_ajp from 2004 (e.g. in this thread[1])
but I guess you're referring to mod_proxy_ajp here?

Where is that statement to be found? The obvious place
http://httpd.apache.org/docs/2.2/en/mod/mod_proxy_ajp.html did not
feature such a note. Also
http://wiki.apache.org/tomcat/FAQ/Connectors#Q2 didn't say that.
Since a quick search didn't turn up something, I'd appreciate a
pointer.

cheers,
-peter

I'd still like to know where on "the Apache site" this statement is to
be found, exactly.
