I’m trying to use mitmproxy as a content filter proxy, but isn`t work. How to use it? Can somebody point me to any manual? I found just [http://docs.mitmproxy.org/en/stable/features/replacements.html](http://docs.mitmproxy.org/en/stable/features/replacements.html) but when i started mitmdump -replace :~q:tester:testerONE and visit [https://en.wikipedia.org/wiki/Test](https://en.wikipedia.org/wiki/Test) nothing changed… Tnx.

`~q` only replaces stuff in requests, not responses - what did you expect to happen?

`~q` means that you only want to apply changes to requests. You want `~s`. 😃

Nice!! Thanks!!

but… next question:  
is it posiible to use lists of replacements from command line? i.e. any file or files with replacements rules like as  
…  
pattern1 -\> replacement1  
pattern2 -\> replacement2  
pattern3 -\> replacement3  
pattern4 -\> replacement4  
…

Sure, you can pass `--replace` multiple times.
