Users complain abut slow video and audio streams when scanning through ProxyAV
Need to effective use ProxyAV for scanning risky content, while avoiding the scanning of long-lived streaming media files which might impair user experience of video and audio streams.
Blue Coat publishes “best practices” for effectively using the ProxyAV for scanning risky content, while avoiding the scanning of long-lived streaming media files which might impair user experience of video and audio streams.
The ProxyAV best practices are available at https://bto.bluecoat.com/doc/10766, specifically section 9, Configuration Best Practices. I cannot attach the entire PDF here, it is 17MB.
The best practices recommend the following settings:
Select Advanced > Intelligent Connection Traffic Monitoring.
Enable the Intelligent Connection Traffic Monitoring (ICTM) checkbox.
Download sample CPL from http://techlabs.bluecoat.com/policy/icap_noscan.txt
Save the file to your desktop, then use a text editor to modify the policy to fit your requirements, and save to the clipboard
To install the policy, Select Configuration > Policy > Policy Files.
Then choose “Install Local File” from drop-down list, select Text Editor.
Scroll to the bottom of the editor window, then paste the contents of your file at the end of the local policy file.
Click Install. A dialog displays, informing you whether the installation was successful.
If necessary, correct any errors in the file and reinstall it.
