Here is a solution I found today.... :-)
1. upload the icon you like to use
Troubleshooting -> Proxy -> Files -> Upload
I used Favicon & App Icon Editor to create such icon.
you have to upload the icon to all proxies you use.
2. Be sure you have the file server functionality enabled on all proxies
Configuration -> Proxy -> File Server
3. Create a Ruleset calles change Favicon.ssl
(we have it in the common rules section at the beginning of our policy.)
This ruleset must only be called in the request cycle.
in GLB_BrowserIcons are the favicon pathes we like to change
We have the following ones:
This will match only in case of SSL Interception. Otherwise the favicon-path is not available by the policy.
The next Hop Proxy is the proxy itself but redirected to port 9999
This will look like:
In case of IE:
In case of Firefox and Chrome the icon will be shown on the surf tab.
We donot intercept Finance sites - so the normal icons will be shown.
Comments are welcome.
