mod_jk 1.2 endpoint cache
I have been testing mod_jk 1.2.5 with Apache 2 and load balancing.
I noticed in the source that mod_jk 1.2 endpoint cache's are disabled
by forcing ep_cache_sz=0. I did a cvs log and could not find any
comments on why this is so. Is there a reason why this is disabled?
Using a cache with a cache timeout sure would be handy for Apache 2
when using the worker MPM.
This feature is documented in the jk docs and I don't see where anything
is mentioned that it is disabled.
Regards,
Glenn

Hey yes you're right, it should be instead :
p->ep_cache_sz = cache_sz;
You commit or I ?

Yes and I don't see any problems.

The build works for Apache 1.3/2.0 on Linux, I should make some tests,
and welcome any Windows binaries for Apache 2.0 ;)

Sorry for the confusion, you are right. It does get set later on.
Did you get a chance to review the minor changes I made in the last week?
With that resolved I am ready to roll another test mod_jk 1.2.5 release.
If that looks ok we can vote on doing the release.

Glenn

Ooops didn't see all the code :
---
ep_cache_sz is correctly set in line 1440
BTW, I wonder why there is a ep_mincache_sz, it's not used elsewhere

What I am saying is that use of the endpoint cache is completely disabled
in the code, it doesn't matter what you set the cachesize to in worker.properties.
Look at ajp_init() in ajp_common.c

I allways set cache in workers.properties but yes we should fix the
documentation to explain that it's disabled by default.
I can do it ASAP

Ok, if you activate it by default, how many entries we'll be defined by
default so I could update documentation ?
In general I'm using 16 entries in cache by worker

mod_jk 1.2.5 release
Posted by Glenn Nielsen <gl...@mail.more.net>.
I have taken care of the serveral minor bug fixes I wanted to get
into the mod_jk 1.2.5 release. But I still have the question
below about endpoint caching.
I would like to renable endpoint caching for use by threaded servers.
Is there any reason to not do this?

Glenn
