Agreed, Hassan... Terry, there's no way anything can determine the
file size until it has access to the complete file. There's no
standard headers to a file to read from.
And tedd, in a similar vein, there's no way you can be sure of the
file size. You could use ActiveX (maybe Java or Flash, but I've never
used those) to find out before-hand, but you limit that code to
MS/Java installed/Flash installed clients, as everyone's pointed out.
So ultimately, you cannot do away with a reliability check on the
server.
If I were you, I would implement an ActiveX based solution to trap the
issue on the client when possible, and then check on the server
anyway.
That's my 2 cents.
