locking question

[szabelin]

Do all asp threads servicing requests run as part of same
app domain? I need a lock at the scope of my web-app; is
the code below a correct way to syncronize blocks of code
in asp.net. Will this work if load balancer (multiple
servers) are used? Thanks!

lock(typeof(string))
{}

or

lock(Singleton.Instance)
{}

Short answer, no. Your web farm will not sync on sections of code. Using
lock() will work within critical sections of code to assure that
simultaneous page requests (aspnet threads) do not access that block at the
same time.
