+=head1 NAME
+
+PLP::Backend::FastCGI - FastCGI interface for PLP
+
+=head1 SYNOPSIS
+
+=head2 Lighttpd
+
+Edit the configuration file (usually F</etc/lighttpd/lighttpd.conf>)
+to enable I<mod_fastcgi> (add/outcomment in server.modules), and add:
+
+    fastcgi.server = (
+        ".plp" => ((
+            "bin-path" => "/usr/bin/perl -MPLP::Backend::FastCGI",
+            "socket" => "/tmp/fcgi-plp.socket",
+        )),
+    )
+
+=head2 Apache
+
+You'll need a dispatch script (F<plp.fcgi> is included with PLP).
+Example F</foo/bar/plp.fcgi>:
+
+    #!/usr/bin/perl
+    use PLP::Backend::FastCGI;
+
+Then enable either I<mod_fcgid> (recommended) or I<mod_fastcgi>, and
+setup F<httpd.conf> (in new installs just create F</etc/apache/conf.d/plp>) with:
+
+    <IfModule mod_fastcgi.c>
+        AddHandler fastcgi-script plp
+        FastCgiWrapper /foo/bar/plp.fcgi
+    </IfModule>
+
+    <IfModule mod_fcgid.c>
+        AddHandler fcgid-script plp
+        FCGIWrapper /foo/bar/plp.fcgi .plp
+    </IfModule>
+
+=head1 DESCRIPTION
+
+This is usually the preferred backend, providing persistent processes
+for speeds comparable to L<mod_perl|PLP::Backend::Apache> and
+reliability closer to L<CGI|PLP::Backend::CGI>.
+
+Servers often feature auto-adjusting number of daemons, script timeouts,
+and occasional restarts.
+
+=head2 Configuration directives
+
+PLP behaviour can be configured by setting environment variables.
+
+=over 16
+
+=item PLP_CACHE
+
+Sets caching off if false (0 or empty), on otherwise (true or undefined).
+When caching, PLP saves your script in memory and doesn't re-read
+and re-parse it if it hasn't changed. PLP will use more memory,
+but will also run 50% faster.
