View 4 RepliesI have an asp.net application running on a web farm that allows users to upload files and download them later via link to that file. Currently, I use Windows DFS to replicate the local IIS directory where the files are stored across the web farm servers. However, as this solution does not scale out, I want to implement a more scalable solution by partitioning the documents. Specifically, say I set up multiple file storage servers (Fs1, Fs2, Fs3, etc.) on the network. Further, let's say I change my upload page to save the uploaded file to one of the file storage servers on the local LAN (based on some logic). I assume so far I am safe with ASP.NET doing this much assuming I have the correct permission for the ASP.NET process ID. The question I have is withregards to download links. When a user gets served a download link to their document (e.g. http://www.testco.com/data/doc1.txt) is there a way for me to "intercept" that HTTP request and underneath the coversserve the doc1.txt from the file storage server (e.g. Fs2) it resides

View 1 RepliesI have struggled with this for the last 2-3 days. I have a tab container control with a update panel surrounding it. On one of the tabs I have allowed the user to upload and download files to a SQL Server database. The upload works fine and the download works fine only when I remove the update panel.
I have tried to implement the solution that's provided at the following location...http://encosia.com/2007/02/23/ajax-file-downloads-and-iframes/I had to modify the code a little bit to fit my scenario but it looks like it would work. Is there another way to download files from a database within a update panel?
If there isn't another way to do this what could be wrong with my code...following the example on the encosia site...
Page starting from [Code]....
The code never gets past the if statement with in this java script. Should I put a trigger on the update panel to force a post back. Any help will be appreciated, java script is not my strong point.
