script to capture data from a client

Hi Everybody,

       I have a question for this group. I want to know wht kind of script or component cane be used to capture data from the clients website.

Scenario: Compay X has many customers (other companies) and X wants to capture data posted to on their clint websites (th form data script can be in any language ASP, JSP, CGI-Perl), bt if somebody posts data , X wants to implement a script on clinets websites which will automatically capture the data and send it to X database. The Question we have is mind is , the clients websites can be hosted on different servers, UNIX, NT, Weblogic . So we should be abe to find a common solution. i will appreciate any suggestions at all. Thanks,

                                                            Sriky
