what is difference between 'SCRIPT_FILENAME' and 'REQUEST_FILENAME' on RewriteModule?
apache, url-rewriting
Solution
The variables SCRIPT_FILENAME and REQUEST_FILENAME contain the same value - the value of the filename field of the internal request_rec structure of the Apache HTTP Server. The first name is the commonly known CGI variable name while the second is the appropriate counterpart of REQUEST_URI (which contains the value of the uri field of request_rec).
