Not that I am aware of. When writing an app to run properly on a web
farm, you should think in the mindset that any given request could hit
any of the servers.
You can use a weaker form of load balancing that will lock a user
session into a specific server - this is called affinity - such that

Hi Brad,
This is exactly what I want and I was hoping that there is something built-
in to do it. Sorry if it sound stupid, but would it be possible to open up
an HTTP request to the second host directly if there is load balancing
software installed. Wouldn't it be intercepted or that's not how lo

If it's not on the same machine, then there's nothing built-in that can do

Response.Redirect will require a roundtrip to the browser, correct? How do

The problem that I am trying to solve is data-dependent routing. I would
like to share state between HTTP requests but I _do not_ want to use the
