When downloading files. During the process of downloading the user can not browse the site anymore. All subsequent page requests hang.

After the downloading of the file has completed the page requests are processes.

The problem is that a file of 30MB could be downloaded for example for 5-10mins.

This is caused by the standard ASP.NET session requests serialization.

To overcome this you should return the old design with a Downloader.aspx page and in the page set the following

<@Page EnableSessionState="false"

This will ensure that during the process of downloading the user session will not be blocked for other page requests.

Best wishes,
Ivo

For both security reasons and reasons of consistency, more recent versions of the Repository module no longer use their own methods for uploading and downloading files, but instead use the dotnetnuke core services. I would imagine you will have the same issues downloading files from the File Manager or UDT or any other core module.

Hi Steve,

I think the problem here is not what method is used for downloading, but where it is used. Because it is used in the Post request of the default.aspx page all user requests while downloading are blocked.

 

If downloading is moved to a separate page which has the SessionState switched off it will not block the other user requests.

Best wishes,

Ivo

Hi,

Are there any advance on this issue.

I think the end user experience connected with this issue is very bad.

"While 1 user uploads a file, no other user will be able to browse the portal, until the upload has finished".
