Sending variable to php script on other server / domain

Hi

Was wondering if anyone knows how to send variables from a emailform on one webserver to a php-mail script on another server?

The emailform works fine when all files are placed on the same server.
Have tried adding: System.security.allowDomain(“http://www.mysite.com”)

I wanne use 2 servers because the main server that hostes my site does not support php …and I wanna work with php.

Hope someone will be able so help?
…it would not only make my day …but the entire week :pleased:
