Better image quality from UMTS using Privoxy
If you are a mobile broadband user you will notice that your image quality is degraded by UMTS. Firefox can overcome this problem by virtue of the Modify Headers plugin. Essentially you need to add two headers to your outgoing request:
Pragma: no-cache
Cache-Control: no-cache
The same effect can be achieved for Internet Explorer and other Windows applications by running Privoxy and adding the following rule to the actions file:
{+add-header{Pragma: no-cache}\
+add-header{Cache-Control: no-cache}}
