I know how to catch 404's etc. in htaccess.
Is there a way I can catch it, display my own output and then NOT return a 404 code to the client?
The reason I ask is because I'm just working on a facebook application (its not an annoying one, I promise) and its almost done. I wanted to do my own 404 error page and it displays fine but then facebook slaps a file not found error message below the content I've provided.
This may be something that needs to be done facebook side if they allow it...
