I have the same situation but it is not as mission critical as the OPs. After reading these posts I got to thinking. We can use a Response.BinaryWrite in a ASP. This bmp can be as small as 1px. Then in the ASP that we are using for the application we could JavaScript a call to it periodically. The src attributes width and height we could set to 0. That would replenish the Session and put actually nothing in the ASP that calls it. Probably a better way but just an idea.
