Until that there is no good way to achive this. But there is a non reliable way of blocking google.com
First allow the Connect method for google.com
Acl CONNECT method CONNECT
acl sslconnect dstdomain -i www.google.com
http_access allow CONNECT sslconnect
Then use an url regex and allow google.com/recaptcha
This way sometimes www.google.com is blocked, sometimes not. But access to recaptcha will always work.
Why we can't block it reliable? Well when browser/client wants to connect to https website then the firsr thing the browser trie is open a ssl tunnel to the FQDN
As soon as the tunnel is up it will request the ressource. May it helps if you add a url regex deny between allowing the connect method and allowing the url www.google.com/recaptcha

Hi Eliezer,
We successfully blocked gmail, google images, google drive and rest all google related. Now we allowing www.google.com and www. google/Recaptcha. We still need to block www.google.com and just allow www.google/recaptcha. Is there a way to do that?
Appreciate your quick turnover!
Thanks&Regards,
Naresh

Hey,
I can try to help you but I do not have enough logs for it.
Also it's not so simple.
Basically you will need to block gmail and google drive themselves in one rule that will not include other google services.
All The Bests,
Eliezer

Hello All,
I installed Squid version 3.5.20 on RHEL 7 and generated selfsigned CA certificates, can you shed some light on how to "Configure regular _expression_ of the Google ReCaptcha URL with ACL".
My requirement :
This requirement is to allow Google's ReCaptcha URL (HTTPS) so associates can successfully use ADP which now utilizes Google's ReCaptcha which is called via an HTTPS URL, without allowing users to access other Google-related services such as Gmail or Google Drive.
Any ideas much appreciated!
Thanks,
Naresh
