Hi there, I am new to this list and new to mod_perl in general, so I hope the more experienced folks will be able to help me. :)
We are starting to test our perl code running under mod_perl. We did go through the porting guide and did everything that was receommended. I am interested in how people setup their Apache 1.3.x servers to run mod_perl'able code. Not, how to get mod_perl to run something, we do that with rewrite rules. I am more interested in config settings that control for performance and stability. I am also very concerned about testing. How do you test a mod_perl system to make sure there is no memory corruption from one instance of an app to another. I have thought about setting MaxServers to 1 and MaxClients to 1, to force the same compiled perl code to be reused, but I am not sure that is agood test. Is there any documentation on testing a mod_perl app? I have yet to find anything. Again, I appreciate the help and I hope to become an active member of this list.
