Lighttpd

1. Format: <errorfile-prefix><status-code>.html
2. -> ..../status-404.html for 'File not found'
   server.errorfile-prefix = "/var/www/htdocs/error"

error-404.html contains php, as do all the other .html files on my website (I use sessions for logging into the website, so I need it like this.)

ALL other .html pages process php just fine, apart from the error-404.html.

To test it, I copied the contents of index.html file into error.404.html.

It simply ignores the php code within the error-404.html page.

For information,
server.error-handler-404 processes php just fine.
