Implement Advanced Webpage Queries in Datasource

I love the \'\'Services\'\' implementation of \'\'Advanced Query Setting\'\' where you can define a sequential set of GET/POST queries against a series of webpages and easily define expected responses and error codes. However, it does not work with URLs that are not on the public internet and it doesn\'t provide the flexibility of datasources to parse the output.

Groovy and command line curl scripts are the only options currently available for private URLs. These are very difficult to build and maintain.
