HTTP Werkzeug is an HTTP send/receive tool, which lets make requests to Web servers and view the HTTP sent and received, and lets you capture the HTTP sent by a browser. It takes care of some of the technicalities for you: Host, Referer and User-Agent request header lines can all be generated for you, POST arguments can be entered into a dialog box, and it is supplied with a customisable selection of User-Agent lines to choose from.
