Hi all,
I'm trying to work on getting some sane AJP proxy configurations using
Apache 2.2.4.
The problem I'm running into is that we use RewriteRules to use regular
expression matching for proxying. In a previous thread on this dev list
there was a discussion around ProxyPass being insufficient for regular
expression matching and that perhaps it should function more like
JkMount with mod_jk.
Specifically the problem I'm running into is something like this:
RewriteRule ^(.*\.jsp)$ ajp://localhost:8010$1 [P]
In this scenario, I don't use ProxyPass to declare a mod_proxy_ajp
worker. There doesn't appear to be a "DefineWorker" directive behavior
that someone mused about in the previous thread. Thus, if I want to
configure the connection pooling characteristics, I can't do the following
<Proxy ajp://localhost:8010>
ProxySet max=100 smax=10
</Proxy>
Because Apache will complain that the ajp://localhost:8010 worker
doesn't exist.
I can create a dummy ProxyPass statement:
ProxyPass /bogus ajp://localhost:8010
it seems to work, but that just looks ugly to me :).
It looks like with:
http://svn.apache.org/viewvc?view=rev&revision=427920
This problem will be solved as the <Proxy> section will create the
worker if it doesn't already exist.
But that's only in trunk. The patch looks relatively simple though, so
any chance of getting it patched back into a stable 2.2.x tree?
The other option that I think will work, but I haven't tested is to use
a balanced worker:
<Proxy balancer://singleworker>
BalancerMember ajp://localhost:8010 max=100 smax=10
</Proxy>
Then declare the RewriteRule to use balancer://singleworker
Basically, it appears mod_proxy_ajp is a slight step backwards in terms
of mod_jk's JkMount functionality. If I'm missing something though,
feel free to slap me up and correct me.
Thanks,
Andy
