Does anyone know of an application or a plug-in that lets you view any/all HTTP requests that get sent out from your browser? I know port scanners have that capability...but I want something that is more "browser integrated", so that, for example, when I click on the submit button for a form, it will submit the data like it is supposed to, but the HTTP request that the browser sent will also get logged, so that I can go look at it.
Anyone know of a tool like that?
