Using curl to see what a browser post looks like

[sfullman]

I am starting to use cURL to send posts and URL's of various kinds. for example:

curl -A "user agent mozilla etc" -b "sessionid=18429481;" -d "username=sam&password=secret" http://www.somewhere.php

what I want to do now, to test what is actually being sent by a browser, is use curl OR PHP to receive a post and know exactly what the browser is sending besides the user-agent, cookie(s) and post parameters, so I can emulate that exactly

Currently, the receiving form is not accepting the login and I'm having difficulty seeing why.

Thanks,
Samuel

The request headers sent by the browser are those in the $SERVER array with the "HTTP" prefix (e.g., $_SERVER['HTTP_KEEP_ALIVE']). Running on Apache you also get [man]getallheaders[/man]. You can also read directly from the input stream [man]wrappers.php[/man].

On the client side, there are things like the LiveHTTPHeaders or Firebug extensions for Firefox that will give you a client-side view of the transaction (and of course Firebug provides a lot of other stuff as well); even plain Firefox gives a "Headers" tab on its Page Info dialogue.
