Issue uploading a large video file

Feb 2, 2009 at 2:56 PM

I have an issue while uploading a large video file in PKS. When I tried uploading a file of size 273 MB, got an error “The security validation for this page has timed out. Click Back in your Web browser, refresh the page, and try your operation again.” after certain period of time.


I found an Microsoft article ( but that applies only to SPS 2003 . So, Could anyone please help me to fix this issue?

SharePoint has a built in file upload limit (the default is 50MB). If you switch to using the Silverlight upload method, however, you won't get this problem. (It sends the file up in small pieces)
