89 PLP::Backend::Apache - Apache mod_perl interface for PLP
93 Naturally, you'll need to enable I<mod_perl>:
95 apache-modconf apache enable mod_perl
97 Setup F<httpd.conf> (in new installs just create F</etc/apache/conf.d/plp>) with:
101 SetHandler perl-script
102 PerlHandler PLP::Backend::Apache
109 =head2 Configuration directives
111 PLP behaviour can be configured by B<PerlSetVar> rules.
112 These can be added to a F<.htaccess> file or most any scope of server
113 configuration. For example, to disable caching for a specific site:
115 <Directory /var/www/somesite/>
116 PerlSetVar PLPcache Off
123 Sets caching B<On>/B<Off>.
124 When caching, PLP saves your script in memory and doesn't re-read
125 and re-parse it if it hasn't changed. PLP will use more memory,
126 but will also run 50% faster.
128 B<On> is default, anything that isn't =~ /^off$/i is considered On.
134 With mod_perlB<2>, any new request will change the cwd for all processes.
135 This means that if you're running files from multiple directories,
136 you I<should not use the current path> for it may change at any time.
138 The bug has been confirmed with at least mod_perl 2.0.2/3/4 on Apache 2.2.3/8.
139 Using this backend on Apache2 is extremely discouraged until this is fixed.
140 Instead, L<the FastCGI backend|PLP::Backend::FastCGI> is recommended.
142 Apache1 does not show any problems.
