This happens when the Scan before delivering option is in use, because this method downloads the whole video file before sending any data to the client. Because the download takes a long time, the client session times out.
To resolve the issue, enable the Deferred scanning option:
- Log in to the IWSVA management console.
- Click HTTP > HTTP Malware Scan > Policies > Virus Scan Global Policy > Virus Scan Rule tab.
- Under the Large File Handling section, select the Deferred scanning option. Do this for all policies dealing with virus scanning.
- Click Save.
- Click Deploy Policies after all appropriate policies have been adjusted.
