When the user requests to download a large file, Vital Security Web Appliance starts downloading the file, and the status page is displayed.
After the file was downloaded and scanned by Vital Security the Internet Explorer prompts the user to download the file, like in the screenshot below.

1. A user doesn't choose to download the file within 2 minutes after the file was downloaded and scanned by the Vital Security appliance. After two minutes, the file is then deleted from the temporary cache, and if requested after this time, Vital Security will begin downloading it again.
   
2. Sometimes, when a user chooses to download a file after it was scanned by Vital Security, IE will request the original file on the web server and not the internal file in the temporary cache.
   In this case, the file will be downloaded and scanned again by Vital Security.
