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