controlling file uplaod size ????

[cosmits]

Hi all
well - the title is very straight forword -
how can i limit users upload file size ?
I guess it is a very common scenario and averyone that comes to
build this sort of functionality in a website has to deal with this question.
is CF enough or do I need a Java object to do the job ?
Thank you for your time

You can't usually find out anything about a file while it's still on the client
machine. When i've validated files, i've usually had to do the upload first
then check the files type, size etc.. after it's been uploaded.

Checks like file type can be done with javascript but that doesn't help with
file size.

If you're allowing users to upload files, i expect the page they upload from
is secured in some way so you won't end up with people uploading huge files
just to annoy you.
