Is there any reason why when a user access a SlickUpload powered webpage via a proxy server, the process gets terminated with a time-out error when the file size is more than 20MB.
Other access without proxy does not show the problem.
Thanks for any help?

Is the proxy server slower, and running into the executionTimeout setting? Perhaps increasing that could help.
Otherwise, I'd figure it's something to do with the proxy. Maybe it's chopping uploads at 20mb or at a certain time. Do other non-SlickUpload uploads through the proxy get terminated at 20 MB or a similar amount of time?

Regular FTP upload is not a problem. It is there proxy software that breaks the packets apart for scanning and then reassembles it for transmission.
Can that affect the SlickUpload processing when the original packets are disassembled and then reassembled?

FTP can't be compared in this case -- SlickUpload only handles HTTP uploads. FTP and HTTP are separate protocols that are handled differently by proxy servers.
As long as the proxy server passes the data properly, SlickUpload shouldn't have any issues receiving it. Many proxies cut off requests at a certain size, or time limit -- this is why I'm trying to track down where the proxy issue is.
Have you tried normal HTTP uploads through the proxy without SlickUpload? Have you tried SlickUpload HTTP uploads without the proxy?

We did tried it with our clients sending the http upload without the proxy and work fine. Wanted to know if there is anything special to configure on the proxy or the web.config settings to prevent the issue from occuring when using a proxy connection.

How long are the uploads taking before they time out? What is your executionTimeout setting in web.config?
Do normal non-SlickUpload uploads work, or do they show the same issues?

If the file selected is over 20mb it times out right away.
Other uploads works fine no matter what size.
We know it is a proxy server issue, I just don't understand why it will timeout on after the proxy software scanned the files and reassembles it for transmission.
When is the "id" generated for SlickUpload transmission, is it on file selection or during the initiation of the upload process?
