Apache 2.2: mod_proxy_balancer does not work as documented?

Hello everyone,

For a production platform, we have plans to migrate to Apache 2.2,
using mod_proxy_ajp and mod_proxy_balancer instead of mod_jk.

Unfortunately, while the "single Tomcat below" case works with no
problem, the balancer does not work at all...

Here is the relevant part of the configuration:


BalancerMember
ajp://tomcat-rod-r7.admin.one2team.rod:8009 keepalive=3DOn
BalancerMember
ajp://tomcat-cdgdev-r7.admin.one2team.rod:8009 keepalive=3DOn
ProxySet stickysession=3DJSESSIONID nofailover=3DOn


RewriteEngine On
RewriteCond %{REQUEST_URI} ^/servlet/ [OR]
RewriteCond %{REQUEST_URI} \.jsp$
RewriteRule ^/(.*) balancer://rod-r7/$1 [P]

With this configuration, sessions do not stick :(

So, looking at the documentation again, I saw that there is a
scolonpathdelim parameter which can be set to On, in order to account
for the part behind the ';' in the JSESSIONID. And indeed, there is
one in the generated cookies.

Unfortunately, when I add this to the ProxySet directive above, httpd
-S says that the parameter is unknown :(

Help :(

ProxySet is only available in Apache 2.2 and later. Are you sure
you're running the 'httpd -S' from the right version of Apache?

Re: Apache 2.2: mod_proxy_balancer does not work as

Hi Francis,

I use mod_proxy_ajp to proxy Pentaho, also a Tomcat application. I
think what you are looking for is ProxyPassReverseCookieDomain so the
cookies are set for the right domain.

http://httpd.apache.org/docs/2.2/mod/mod_proxy.html#proxypas sreversecookied=
omain

Let me know if you want me to share my configuration files.

Yes please! In the meanwhile, I have found a way, which is to add a
route=3D parameter to each BalancerMember. I do set this parameter as
jvmRoute in the AJP connectors on the tomcat side, I didn't think it
would have an influence here. But it seems to have...

Yes, this is Apache 2.2. 2.2.3 to be precise (the one bundled with rhel5).
