I thought I had finally figured out how to control the downloads from my page. I was having issues with large files, but after much research I came up with the following code. The download seems to proceed without issue, but never terminiates. The byte count stops incrementing, but the dowload dialog never closes. (Until I hit cancel.) What's keeping the download from ending properly? I'm pretty close to finishing this app - any help is greatly appreciated. Thanks.

Here is the my theory.
Add ContentLength: to the header.
Response.Append Header("Content Length", Filesize.tostir ng() )
Let me know if it worked.

I appreciate the response, but that didn't do it. I was hoping it would at least address another item I posted regarding download progress, but it didn't do that either. Any other ideas?

FYI - This only seems to be a problem with larger downloads. The smaller downloads work just fine.

Jerry,
If you solve this, it will be amazing. I spend days last week researching ths issue and read about developer teams spending months trying to get a solution, and finally did (but in a very messy and complex way). I hope you get it though...we will all be happy!!!
Earl
BTW, with the current solution you have so for, does the dowload dialog pop up to the client right away?

When I tried it with Response.WriteF ile, larger files just ended up with a "Page Not Found" error.
The code below seems to work - there's something strange going on. I tried it with three files:
File1: 66,854K
File2: 74,902K
File3: 158,262K
Files 1 and 3 work without a problem. File 2 hangs every time. This is really making me crazy! What's the problem with 74 Meg if you can handle 158 Meg just fine?
Anyone? Please!?!??!?!

I wrote a file download module for my website. The reason for the file
download module is that my website downloads work on a credit based system.
So I need to keep track of and limit daily downloads.
It uses fpassthru() and some headers() to send a file to the requesting
user. The get.php file that I wrote (the file download module if you will)
