When a user downloads a file from the ICAP proxy server, no feedback may be displayed about the progress of the download until the download is completed. If you use BlueCoat ProxySG as your ICAP client, you can improve the end user's experience by enabling the Return patience page, which displays the progress of the download. The Return patience page is disabled by default.
In the BlueCoat ProxySG Web UI, go to the Configuration tab.
In the sidebar, go to Content Analysis>ICAP.
On the ICAP Feedback tab, select Provide Feedback and enter the number of seconds before feedback occurs.
To enable feedback about download status, select Return patience page.
The patience page displays the URL, the size of the download, the amount downloaded, and the elapsed time since the download began.
