Dear Amos

Have no such acl in my conf:

Dear, i’m using squid 3.2

Sometimes the Squid-cache log correctly the SSL connections to web sites

But when i’m browsing to https://www.youtube.com there no entry in squid
access.log ??
Is there any limitation that ban squid to log https requests..?


Not unless you configured such a ban or SSL-bumped those requests.

log_access - to block a request from being logged anywhere.

access_log <log> [acl acl ...] - to block a request from being logged
to a specific log.

SSL-bump will log the bumped requests inside the CONNECT tunnel as
https://* URLs individually, instead of the overview CONNECT (varies
with squid version whether the CONNECT is *also* logged).
