[squid-users] How to enable caching for https websites on Squid

[Sekar Duraisamy]

Hi Amos,

Thanks for your reply .

"To cache encryption protected content you must first remove the
encryption. That destroys the "anonymous" part completely."

Could you please provide little more details about this line about it
destroys the anonymous while we decrypt the encryption and enable
caching for https?

 https caching for anonymous proxy is not recommended?
