Is there anything within Seaside that helps to POST data to another website?

I want to build a very simple site (as a learning exercise), that displays a form, captures that data, modifies it slightly (on the Squeak server) and then saves it to a totally different web server - just by using a REST call. 

On the face of it, it seems as though I need to use HttpSocket to do the data saving, but before I start digging into that, I wanted to check whether there was anything within the Seaside framework that would help me.

Thanks
