How to send parameters to a URL via http?

[Brian Burridge]

I have a very simple need for cocoon, but I haven't seen anything yet that can do this.

I need to be able to send all the request params (the RequestGenerator xml would be fine to as an HTTP param) to a url via http, and  then receive xml and use it in the pipeline.

I see the File Generator can get xml from a url, but I don't see a way to be able to include any parameters, or even better include the xml the RequestGenerator can create, and pass that as a parameter.
