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 Settingsā€¦ 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

Make sure to replace "BSNEEStorage" with the name of your Storage site.
