Just turn off output buffering immediately before the call to Readfile(). You can easily parse command line arguments into the $_GET variable by using the parse_str() function.

See the Supported Protocols and Wrappers for links to information about what abilities the various wrappers have, notes on their usage, and information on any predefined variables they may provide. Obviously first use $rPage = fsockopen() and fwrite($rPage,) and such, after which: If, like me, you're in the habit of using fopen(". The only way to read postdata will then be through the php://input stream wrapper. Note : If PHP is not properly recognizing the line endings when reading files either on or created by a Macintosh computer, enabling the auto_detect_line_endings run-time configuration option may help resolve the problem. Anyone with a modicum of networking experience can run a TCP trace and see the 302 Redirect response, as it is actually a response received by the client browser; the browser then makes a subsequent http request for the URL provided in the Location header.
