I am using ActiveVFP in IIS. IIS is multi threaded web server. I use ActiveVFP scripts which are prg files but with a different extension. I have not compiled my VFP code as a COM exe/dll.

If two or more users call an ActiveVFP script file (a process) at IIS, is it possible that IIS will hold the first user thread anywhere before completion and call the second thread from other user ?

I am using local variables and since i am not using any VFP form so i think, vfp datasession will be default i.e. 1.

How can I protect my variables values / table record pointers / common files etc from first thread to other threads ?

How can I add "Critical section support" in my ActiveVFP script files ?

TIA
