A while back, I wrote about dealing with the Apache / FastCGI error ‘Primary script unknown’ when trying to access non-existent PHP files. Bots often do this trying to test for vulnerabilities, and it can fill up error logs and be annoying to look through. In that post, I fixed the problem through mod_rewrite and a RewriteCond. For PHP 2.4+, there is a more broad and likely more efficient solution using the <If> directive. It will work for all virtual hosts on a server.

I thought it was related to this and this, since I’m running under FastCGI on Dreamhost, but attempting to set a Status header didn’t help. Setting a regular response header in a plain PHP file does work, in fact. If I use ‘mod_rewrite’ to write another URL to load that same plain file, however, the status shows as ‘200’, so it must have something to do with ‘mod_rewrite’. Must get to bed though, so I will have to try another day.
