POST without a button

I have an HTML/Javascript file which has a form in it whose action is to call my PHP4 file. After PHP4 stuffs some of the data into a database, it needs to POST to a remote html file. The PHP4 file is invisible, generates no HTML except in the case of an error. How do I invisibly do another post without putting up a submit button? I thought of using header("location:"), but I understand from the manual that headers should go at the very top of the file, and I want the entire file to execute, then jump to the new address. ************************************************* Ron Newman Troubadour Technology http://www.imt.net/~ronman/ *************************************************
