Description

When media range retrieval requests have been enabled, several HTTP requests are sometimes sent when downloading a single media file. These requests use the Range HTTP header. As a result, the Download page event that is assigned to a media item triggers each time a new request is sent.

Solution

To resolve the issue, for Sitecore XP 8.2.7 or earlier, download and install the following patch on Content Delivery servers:

1. Place the Sitecore.Support.372406.dll file into the /bin folder.
2. Place the Sitecore.Support.372406.config file into the /App_Config/Include folder.

Note: The patch disables checking the Range HTTP header value when tracking additional HTTP requests to the same file.
