WebScarab Template - Bean Shell














In the spirit of WebScarab templates, here is a fresh template for the bean shell. Wait, you just put out a template for Manual Request, how is this different? Good question. The Scripted feature allows you to build and send custom requests. The bean shell lets you modify all requests/responses sent through WebScarab. So, if you turn on WebScarab and start browsing the web, your bean shell code will execute for each request/response.


Copy the source code below into the bean shell and hit 'Commit'. The output file prints to c:\ so change that as desired.
