Hello,

I have a process within my MVC 2 application that takes a large amount of time and alters many rows in the database in the process.

There is a chance that two or more users could attempt to perform this action at the same time, which would lead to undesirable effects.

Is there a way to set a global flag somewhere within asp.net that I can check against all requests to see if the action in question is currently being executed? (a bit that I flip prior to running query, and then then flip back on completition)

Or is there a better way of handling this situation?

Thanks
