[waxbird]

I think there must a idea to let one ASP page /limit one user visit/ at one time/...
Who ever do this?
Can we do it?

[plumsauce]

create an application scope variable

grab a lock on it at the very top of the page

[waxbird]

but this page's operation need long time,im afraid if lock it ,other one can't read the global applications.

you are placing a lock on a particular global
variable, not an application. different thing.
