Re: Managing to kill httpd (why?) semi-solved
Just letting you know the versions of stuff:
Perl 5.6.0
mod_perl 1.24
apache 1.3.12
I've played around with the WebAPI loader and got it to stop crashing (good)
but the object isn't cached (not good - I need POST data in many places and
can't depend on PNOTES since that may not be available on the target platform
(CGI)).
Any idea?

Most of the sites that I produce have a lot of static content and just a few dynamic pages and the exceptions are nearly 100% routed through mod_perl, whichis fairly easy. I don't use mod_rewrite for the former, the following suffices: ProxyPass /mperl/ http://www.url.net:8000/mperl/ ProxyPassReverse /mperl/ http://www.url.net:8000/mperl/ Then anything that's accessed under /mperl is treated by the mod_perl backend. For the latter I use various combinations of FileMatch or mod_rewrite depending on the setup. It's usually fairly simple. >I'm reading the mod_rewrite guide right now and my head *is* >spinning. It's quite a good guide but it has to get one's head spinning. Remember the first time you read about Perl regexes :) -- robin b. Brain damage is all in your head.
Script executing error.
Dear All, I have configured a web server. Presently I am able to execute shell script on the browser except .shtml .cgi .pl on the browser..please let me know if anybody knows how to or make the changes in httpd.conf file or any other related file to execute the perl and cgi scripts on the browser.

The problem with conditionals and includes is that the light/heavy httpds tend to have almost nothing in common except the DocumentRoot and they may not even be on the same machines. Some sort of template mechanism might work with postprocessing to spit out the front and back end config files, but then you have yet-another-syntax to learn. I usually just open both files in different windows and cut and paste to make any common changes. Les Mikesell [EMAIL PROTECTED]

Perrin, Robin, et al at least I don't feel alone on this one :) now let me seize the opportunity and (while you're around, having admitted you're using a 2 tiered apache setup,) ask you if you are doing the mod_rewrite/mod_proxy trick, and how were you able to pull it off. I'm reading the mod_rewrite guide right now and my head *is* spinning.

We have a file with the varying bits of info in it (MaxClients, MaxRequestsPerChild, etc.) and a small program that accepts a name to use as a key into this file. It takes the hash of data from the file and runs it through the httpd.conf template using TT, which allows us to do loops, conditionals, or even in-line perl if we wanted to. This all happens as an installation step, so it's an extra step compared to IfModule tricks that happen on the fly. It does have an advantage in that you can use it to handle configuration variations for QA and development systems. - Perrin

It is indeed a bit of a configuration nightmare when vhosts add up (even though it's well worth the trouble). What I do is use both IfModule to merge both confs and mod_macro to factor out the repetitive bits. It works quite well and at any rate the win of splitting into two httpds overweighs the configuration overhead, but I'm still not completely happy. Half of me is thinking about using Include to try and break up the conf file into smaller bits and the other half wants to write something that would help automate the configuration completely. It's possible on the mod_perl side if you write your conf in Perl, but it's more troublesome on the plain Apache side.

That could work. So could , where you start your heavy httpd with a -Dheavy. Where I work, we use Template Toolkit to generate variations from one httpd.conf template. - Perrin
One httpd.conf for both apache heavy and apache-light [IfModule]
hi, I'm trying to build a 2 tiered Apache setup, with one light httpd, one mod_perl httpd and a mod_php4 httpd, all running on different ports on the same machine/IP. Right now I'm solving the mod_rewrite mod_proxy stuff (I want the light httpd to transparently proxy requests to the 2nd tier httpd daemons). What I see in the not-so distant future is a hell of a configuration nightmare. From the start, this box should be hosting about 30 vhosts, and I don't really want to keep them in synch across 3 different files. So I thought of using a single monolithic vhosts.conf with lots of IfModule sections. Is anyone using this directive? Am I getting in a mess? martin

PerlLogHandler not being run ?
Hi all,
After having perused the Eagle book, Stas's Guide and archives of
the mailing-list, I see no lights on my problem.
Maybe I'm doing something so silly that you will see it right on.
My setup :
Debian Linux with apache 1.3.9-13.1 and mod_perl 1.21.2309-1
I've put :
PerlLogHandler My::Handler
in apache's httpd.conf
but it is not runned by Apache !
I have Trans,Authen,Access,Authz and Main handlers all working fine
in the exact same situation.
I believe Debian mod_perl package is compiled with EVERYTHING=1 and
that's what /perl-status told me also.
If, from another handler I call the My::Handler::handler() subroutine
it is correctly executed. So my code seems OK. And perl -c is happy
too. And apache restart is happy too.
But Apache doesn't want to execute it.
It's the same if I put it in a PerlCleanupHandler.
I even tried :
sub handler
{
warn("YYY\n");
}
Nothing written, nowhere...
What do I miss ?
Is there a delay between the Main handler and the Log Handler during
Apache's run ?

Have you looked at embperl? The latest version allows you to map the filesystem/URL path to a hierarchy of objects so you can create a top level default and only override the parts you want to change as you go down to different sections - without changes in the page itself.
