Did you changed pfsense gui port to other then 80,443?

Can you check your config to see if there is missing a space or hosts are misconfigured?

acl AccraHelpDesk url_regex -i accra.ca/http://helpdesk.accra.ca.*$
acl AccraHelpDesk url_regex -i accra.ca/http://helpdesk.filopto.com.*$
acl AccraHelpDesk url_regex -i accra.ca/http://accrahelpdesk.accra.ca.*$
acl AccraHelpDesk url_regex -i accra.ca/http://support.accra.ca.*$

EDIT:

There are some bugs using only squid-reverse function. I'm checking and fixing it on a clean 2.0.1 install.
I'll release a fix when I get it working…

I've pushed some fixes, please re install the package, check mappings tab and test again.

answers to questions

no I have not set the pfsense gui port to anything else but what is the default port 80 & 443
reinstalled latest package and checked the mapping tab, see no error and nothing is being rerouted.

Nothing is showing in the Real time tab (log) I am presuming nothing is getting caught since I am not being redirected.

What does the ^http://www.mydomain.com/.$ format provide more than the HTTP://accrahelpdesk.accra.ca ? Should I use it like this ^http://accrahelpdesk.accra.ca/.$ instead of the straight URL?

Thanks for the help, Willing to try any of your fixes, just let me know.

@cjbujold:

So, change it and disable automatic redirect rule on system advanced

You can use any combination, my suggestion is:
^http://accrahelpdesk.accra.ca/ or just accrahelpdesk.accra.ca

Did you enabled squid logs on proxy server config?
