I have this ques开发者_JS百科tion https://stackoverflow.com/questions/2688464/ajax-request-from-net-give-me-unexpected-results

and i am using tamper data but i am sure firefox is formatting the data in ways i dont understand. Is there a tool i can use to check firefox post request? and perhaps my C# post request?

Recommend you download the Firebug plugin for Firefox, this will allow you to debug on the browser side more easily.

Also take a look at Wireshark (or similar) to inspect the HTTP requests that are actually going out onto the network.

Fiddler is a widely used web proxy/debugger - you can easily see incoming and outgoing requests with it. It can be used with all browsers.
