Subject Problem with parent.config
Date Sat, 14 Jan 2017 08:10:47 GMT
Hello

  I am finding difficulty in setting up forward proxy. I have made the
following entry in my parent.config

url_regex=google go_direct=true

What I expect is - in case a request comes with url with google, it should
directly forwarded to the destination ( www.google.com ).
But it doesn't work like that

The following is the log snippet .
