Just curious what everyone thinks of REST:

Architectural Styles and the Design of Network-based Software Architectures
REST wiki

REST seems to have found a home in the web services domain. Is there anything there that we can apply to user interface oriented web applications?

REST mandates that are particularly troubling for end user oriented web applications:
  • GET requests must have no side effects.
  • No sessions.
  • No cookies.

I'll be the first to admit my understanding of REST is limited.
