What is the best way to design a HTTP request when somewhat complex parameters are needed?

Question

I have some web services that I am writing and I am trying to be as RESTful as possible. I am hosting these web services using a HTTPHandler running inside of IIS/ASP.NET/S

Answer 1

I'd aim for HTTP POST. It's nicely tokenized when it gets to PHP (or whichever you're using) and it doesn't have the size limits the others have.
