Could the Re-Entrant logic be put in an IDiposable-struct, that implements IDisposable. Where struct-constructor setup the blocker, and the dispose-method removes the blocker.

Then the IDiposable-struct can used in a using-statement to protect the lookup.

That sounds like a great idea. We will do that.

Yes see that TryGetLock must be changed to static method that receives httpContext as input parameter. Can this be done?

[bakgerman]

changed as requested. I did not know that about struct, so I learned something new.
