Well... Technically...<BR><BR>GET: Depends on browser. IE on Windows, around 2000 chars, but that also includes the "http", domain and filename... Don't bank on more than around 1000 available for your use and you SHOULD be ok. Bear in mind other browsers have LESS SPACE, and your stuff WILL BE TRUNCATED!<BR><BR>POST: Huge. You can submit huge files through post. If you're submitting that much data, you're going to fall into the 100K Request.Form() element bug, so that's the thing you need to look out for. Basically, each form element (each input on the form) can only have 100K of data, or you'll get stack overflows when you try and retrieve it. (You can still get it using Request.BinaryRead).<BR><BR>Craig.
