Writing your own LINQ extension methods?

Preventing DoS attacks with puzzles

So when a web service is getting too much traffic it starts returning the 503 status code. Well written services also return the Retry-After header hinting the client when it should come back again. Good behaving clients then respect that or will back-off by themselves to make sure the server is not getting too much traffic.
