RE: when to mod_perl?
You don't mention what OS you're using, but with Linux, 256mb just running httpd seems quite generous whether you're using mod_perl or not. From what I know, mod_perl is going to give you more performance on any given box. And now, I can't resist: When should you? Why, when you're in the mod of course ;) David LeBlanc Seattle, WA USA -Original Message- From: md [mailto:[EMAIL PROTECTED]] Sent: Monday, June 24, 2002 19:22 To: [EMAIL PROTECTED] Subject: when to mod_perl? Hello, I'm working on a dynamic site that I originally thought I would do with mod_perl. Now after reviewing the requirements and available hardware, I wonder if mod_perl will be my best solution. The machine will not be a huge box (though I wasn't provided much in the way of specs) and will only have 256M of RAM. There will be static content, incuding 5-10 images per page. The client has only given me sparse information, but claimed that he currently had 4,000 unique visitors a day and wanted to move to 10,000-15,000 unique visitors per day (he didn't give me page view stats). I may or may not be able to set up multiple instances of Apache. Given limited hardware (esp. RAM), am I better off to go with mod_perl (larger Apache processes with limited RAM) or CGI (smaller apache processes but the usual cons)? Thanks... __ Do You Yahoo!?

RE: Sticky Pages.
Ok, now i'm totally confused. From the top: 1. I have the following (and ONLY the following related to modperl) in my httpd.conf file (of course there are other regular apache directives too): LoadModule perl_module modules/mod_perl.so AddModule mod_perl.c In a subdirectory there's an .htaccess file containing this reference to modperl: Files * SetHandler perl-script PerlHandler Apache::Registry Options ExecCGI PerlSendHeader On /Files These are the only references to modperl that I have. TWiki is the only perl app that I run, so I thought I only needed the lines in the .htaccess file. I have changed the line reading PerlHandler Apache::Registry to Perlhandler Apache::PerlRun as you suggested, and it results in the error I reported to you.' I would really appreciate it if you would tell me exactly what I should do to implement this alternative you've suggested.

Stan; I tried using Apache::PerlRun and got this in the error log: [Thu Jan 03 10:40:24 2002] [error] Can't locate object method filename via package Apache (perhaps you forgot to load Apache?) at J:/Perl/site/lib/Apache/PerlRun.pm line 24.

I'm not familiar with this sw, but I'll assume that it remembers the state (the last visited page). Does Twiki claim to be mod_perl clean? It's probably not coded with persistency in mind or happens to have the closure problem under Registry. As a temp workaround use Apache::PerlRun instead of Apache::Registry.
