PHP Proxy Script for cross-domain requests

31 May 2007

I wrote this php-proxy-script and have been using for different purpose (loading cross-domain data like text, xml, swf, image, etc. or for YouTube REST API  in flash, flex applications).

People keep asking about proxy-scripts in forums to manage various things (cross-domain AJAX issues). Download the proxy.php.txt, and use to solve such problems. You can also fork it on Github, and improve it.

Usage:

http://yourserver.com/proxy.php?url=[&mimeType=]</pre>
Examples:

To load XML/Text:

http://yourserver.com/proxy.php?url=http%3A//abdulqabiz.com/blog/index.xml
To load a SWF (binary-data):

http://yourserver.com/proxy.php?url=http%3A//abdulqabiz.com/files/some.swf&mimeType=application/x-shockwave-flash
