If Devices Are Not Downloading Presentations with Special Characters

It is possible to upload presentations that contain certain special characters (e.g. "+"), but the Storage server will return a 404 error to devices that attempt to download the presentation. Use one of the following workarounds to fix this issue:

Add the following parameter to the root Web.config file of the BSNEE Storage site, which is hosted on IIS:

<system.webServer>
     <security>
          <requestFiltering allowDoubleEscaping="true"/>
     </security>
</system.webServer>

Use the IIS Manager UI.

1. Select the storage site.
2. Double-click Request Filtering in the IIS group.
3. Click the Edit Feature Settings… link on the right pane.
4. Check Allow double escaping and click OK.

Enter and run the following in the command line: %windir%\system32\inetsrv\appcmd set config "BSNEEStorage" -section:system.webServer/security/requestfiltering -allowDoubleEscaping:true
