IIS protection

[John Wood]

I have a couple of questions (that may be more IIS related):

1. If my ASP.net application gets caught in an infinite loop... how does the
process ever get terminated? Does it time out?
2. If my ASP.net application consumes all resources (eg. creates a bunch of
brushes it doesn't release), can this affect other processes running on the
ASP server at my hosting site?

Thanks,
John

This depends largely on what version of IIS you are running. IIS5, it will
take down the process since there is no true isolation mode. IIS6 achieves
true isolation so strained resources only affect the particular application
pool. Note that high cpu will affect the server since it is necessarily a
shared resource. IIS6 allows for the recycling of the application pool based
on particular settings so it is possible to protect other application pools

Thanks for your response.
Is there any protection against CPU usage at all?
How do web hosting companies typically maintain the CPU usage across
applications, and ensure that one application isn't hogging the machine?
