The following set of rewrite rules rewrite any URLs formatted as http://foo.example.com/bar to http://example.com/mysubs/foo/bar.php. This all works fine except if I have a subdirectory named 'blah' in the original URL such as http://foo.mydomain.com/blah/bar, then it will rewrite it as http://example.com/mysubs/foo/bar (without the blah subdirectory) when what I need is the url to be rewritten as http://example.com/mysubs/foo/blah/bar.
So, what do I need to change to make this work correctly?
