If you are asking how to check the file size on the client, that's not going to happen. Security concerns prevent client code from knowing anything about the file system.

How on Earth would Ajax help?

You might be able to use an Applet -- but the user will have to accept letting the applet check the file system. There's no guarantee that they'll say yes.

On the server side, can't you just check the content-length header and refuse the connection if the size is too large?

I believe the Apache file upload product provides something which allows you to do that. I don't have the documentation handy but it shouldn't be too hard to look it up for somebody who does have the documentation.

I had used the request.getContentType() in my condition to check the file size it will take < 1 sec now to give me the content length but when i redirecting it it ll take 5 min to redirect

Can you please check the API and see what request.getContentType() returns?

Is it giving you what you expect?
