[squid-users] key-value pairs output from external helper

[Sreenath BH]

Hi

I added code to set "tag" in acl helper, as follows:

print "OK tag=abcd\n"
and I was able to add a  url_rewrite_extras
as follows:

url_rewrite_extras "%et" and it was passed to the url rewriter.

So, I guess it is working.

thanks for the help
