[Privoxy-users] Help filtering text or syntax in a web page.

[Terry Clarke]

Hi,

I tries blocking the domain. The call to the blocked site still goes 
through. Can you please send me the instructions to tell theprivoxy to 
remove URLs from pages.

Can I use the privoxy to block things in the web pages like third party, 
scripts, xhr etc...

Jason,
