Check existence of a file

[dgage]

Hello all -

I hope I am posting this in the right area.
I was wondering if someone can point me in the right direction here. I am looking for information on how to program my app so that it can check for the existence of a file on a web site that I manage.
If there is a tutorial or something that someone knows of that can help me to understand how to write this, I would appreciate it.

Thanks -

Doug

There's a function in post 2 of this thread to check this. It just attempts to open a connection to file and close again, not actually downloading the file.
