I have a particular situation with code i'm inheriting which is using shtml server-side-include, however I'm attempting to add some very simple login functionality to the site so I need to include a session check in PHP.
However my the only configuration I can do to the server is the .htaccess file.
I can get the server to parse the shtml as PHP using htaccess, OR use SSI however I cannot get it to parse it as both.
