Yeah, that code would have problems.

One other thing just remembered is that technically it is allowed that the path part of the request line can actually be a URI.

    GET http://hostname/a/b/c HTTP/1.0

This would yield:

    REQUEST_URI: 'http://hostname/a/b/c' <http://hostname/a/b/c'>
    SCRIPT_NAME: ‘'
    PATH_INFO: '/a/b/c’

Obviously I didn’t even mention the % encoding issues as part of SCRIPT_NAME part as you are obviously aware of those being an issue in PATH_INFO at least.

Lots of fun.
