Looking for mod_perl docs on writing logfile handler.

Sihal has asked for the wisdom of the Perl Monks concerning the following question:

Fellow monks,

I understand that with a Perl*Handler I can intervene at any stage of Apache's processing of my request.
But, not being very familiar with the Apache's callback hooks mechanism, and not being that much familiar with Perl*Handlers, I don't know how to do the simple following thing: writing my own log with a PerlHanlder instead of letting Apache do it. (Or injecting aditionnal info in the logs that Apache generates, like the value of an environement variable.)

If somebody could point me some links to a good explanation of this aspect of mod_perl, I'd be very glad. (the mod_perl documentation at perl.apache.org isn't helping, or maybe it's just me. )

How about the logging section from Writing Apache Modules with Perl and C. Or the online chapters of the mod_perl developers cookbook. -derby	[reply]

I do customise Apache's log. But I want to pass an env variable into the log, with isn't possible from CGI. Thanks for the online books links I wasn't aware they could be on the net. :-)	[reply]

There are 3 good mod_perl books i can think of: Practical mod_perl mod_perl Developer's Cookbook Writing Apache Modules with Perl and C But, have you looked at Apache::LogFile yet? That might be all you need ... jeffa L-LL-L--L-LL-L--L-LL-L-- -R--R-RR-R--R-RR-R--R-RR B--B--B--B--B--B--B--B-- H---H---H---H---H---H--- (the triplet paradiddle with high-hat)	[reply]

Well I'd rather not use any books (not that I don't like reading but the company won't buy them). I'll have a look at Apache::LogFile thanx, but I think I already peered into it.	[reply]

You could also simply customise Apache's access log entries.. Module mod_log_config cheers, J	[reply]
