- Idle processes will be killed by FastCGI after the idle-timeout is reached. You'll see a warning in the Apache error log when this happens. This is normal as long as the exit status is 0.
- php5.fcgi must be executable by the webserver, and the directory its in must be +ExecCGI. (The PHP files themselves don't need to be executable.)
- If php5.fcgi is not executable, or if ExecCGI is not enabled, you'll get a 403:Forbidden error.
- You need a copy of php5.fcgi in the document root of every VirtualHost.
- You can add arguments to the 'exec' to tweak how php runs. You can, for example, have a separate php.ini file for every directory on your server.
- Not absolutely necessary to do it this way. You can copy the php binary into a cgi-bin directory if you're more comfortable with that.
