I've written a web interface where a user enters credit card information, and this information is sent to a CGI script (Using method=POST). The CGI script then sends back an HTTP response with some "input type='hidden'"... values (So it displays a blank screen). My question is this: Is there a way for PHP (Or anything else) to intercept this HTTP response, so that I could parse it and display the hidden values on my page?
As a note, I can't modify the CGI script, because I'm working with the viaWarp merchant software.
