Host-rules google chrome, adding configuration

I appear to be answering an old question, but anyway...

You posted:

"/path/to/chrome.exe" --host-rules="MAP * www.domain.de, EXCLUDE *.youtube.*", *.last.fm"

I think the quoting is messed up in your example. It should be:

"/path/to/chrome.exe" --host-rules="MAP * www.domain.de, EXCLUDE *.youtube.*, *.last.fm"

Besides fixing quoting typo, you should write EXCLUDE before each excluding domain:

"/path/to/chrome.exe" --host-rules="MAP * www.domain.de, EXCLUDE *.youtube.*, EXCLUDE *.last.fm"
