HTTP.SYS Kernel mode driver
What is the big deal with HTTP.SYS in IIS 7? From what I understand, it is low level which is good for security. Why? There is no context switching which could be expensive. Why? Please explain. Thanks!

Requests for cached responses are served without switching to user mode. Kernel-mode request queuing.
