In a clustered environment does Cache.Remove() kill all instances of the
cache item, or does it just kill the item from the box that the code is
currently executing on?

For example, suppose I have two boxes within a cluster. If a request gets
served up to Box 1, and Cache.Remove(foo) is executed, does foo get removed
from both Box 1 and Box 2, or just Box 1.

Hello,

The Cache object is restricted to being used only within an application
running on a single machine. Therefore, I think Cache.Remove() only
remove cached objects on one server.

Luke

that's correct

so how to easy migrate asp.net project that uses cache and session objects
from single server to cluster servers?

Thank you very much for your response. This explains a lot.

Do you know where I could find some information, or possibly sample code,
that would clear the Cache for all servers in the cluster. The only way I can
think of is to actually run Cache.Remove() on each server. That would force
me to find a way to make a request to each server. It seems like there must
be a more elegant solution.

Yup, that's pretty much it. Or another cheesy way is to force an application
pool recycle. You can actually generate the recylce thru a script app that
runs on the servers. If you google, you should be able to find the app pool
recycle script.

Firstly, you are limited by the technology. If you need to share cache in a
cluster, it needs to be in the database or in a third party application that
makes this functionality available.
