Web services when data is not necessarily forked back

Sorry, trying to figure this out. A web services client sends a request for data. However instead of Rails (web services server) sending back
xml for the client to render, the web services server actually renders the data, would that still be a web service ? Hope this isn’t a confusing question.

My objective is to have Rails acting as the web services server but to deliver the data on request.

TIA

I'm not sure what you're trying to do. You want to make a request to
the web server and then have it return a web page? You certainly don't
need web services for that...

A web service doesn't have to return data, and it would be possible to
have it return a string of html if you wanted.
