Cross Platform Perl RePOST/ReGET

I need a script that takes GET parameters and/or POST parameters depending on the request method and forwards these to another server to be handled... this is NOT a 301 redirect. When the script receives a request in either GET or POST form it needs to read a text file on the server containing a unique code (account # type of thing), appends that unique code into a new HTTP request (along with the original requests GET or POST parameters), makes the request to a different server, returns the results of this 2nd request as the response to the original POST or GET. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ## Platform Linux Solaris Windows
