As per my previous question, I need to redirect an HTTP POST request to a different server. I believe this can be done using HTTP response headers from php, but I understand the POST request will become a GET request. My question is what happens to the body of the HTTP request? is it discarded, or will it be converted to be part of the GET request's query url?

i.e. if a POST is made to http://mysite.com/handler.php and I redirect to http://othersite.com/handler.php will it automatically become http://othersite.com/handler.php?param1=hello&param2=world

The POST data vanishes. Unless the redirecting script takes steps to push the POST data into the GET's URL or into a cookie, the data's dead and gone.

This is somewhat by design. Most browsers limit the length of a URL, and POSTs have effectively no limit to the size of the data being POSTed, so you wouldn't want that 500megabyte file you just uploaded appended to the GET url's query line.

If you are using CURL to redirect such a request, it is regarded as a distinct, new HTTP request that is not related to the original one at all. The only data that gets passed along is that which you explicitly pass in the query string.
