On the side 'http://ubuntuusers.de/' I want to replace the search with 'startpage.com' to 'duckduckgo.com'. I have all the examples from the Help chapter 8.5.31 (http://www.privoxy.org/user-manual/actions-file.html) tried, unfortunately it does not.
Many users (http://forum.ubuntuusers.de/topic/habt-ihr-neuerdings-auch-start-page-als-suchfu/) are with the integration of 'startpage.com' not happy and would probably welcome an individual setting.
Thanks fore help!
The search function uses a https:// URL so Privoxy will not see the
path and can't use its content for redirects.
Allowing Privoxy to filter encrypted content is on the TODO list:

In the meantime you could replace the search URL itself using a content filter.
