Hi, We have just made one of our products available via download ( 385MB zip file) from our DNN Portal. We have many other files available for download (both zip and pdf) and have never had problems before, but they are all significantly smaller.

Users are reporting that they are unable to download the file, using a variety of browsers, browser versions and setups. If internet traffic is light tests have shown this file downloads fine in around 30mins. If internet traffic is heavy the file typically bombs out at between 40% and 70% and/or 3 hours.

The file is in a secure file system within DNN (so has the .resources appendix to prevent people getting straight to it) and is accessed by a LinkClick URL so I cannot use any of the free download accelerators available which have a resume function to help users download it. Could the secure file system or the LinkClick be causing problems?

I have made the file available to selected users via an IFrame implementation of JSCAPE which has a resume function and although it took a long time it did succeed - however this is not a viable long term option since each user has their own folder and I don't want to put the file in everyones folder!

Any suggestions on what to try next would be most appreciated. We have looked at settings within DNN but timeouts only seem to apply to sessions (1 hour) or uploads (3 hours) - nothing on downloads.

Thanks, Sam
