Hi, sorry for the late response and the ambiguity in the initial post. That fact is unrelated to the concern being raised in this thread AFAICT: The concern is _not_ whether Squid verifies the target of the SNI-based CONNECT during step3. The concern is whether Squid verifies the target of the

[squid-users] hostHeaderVerify with SNI in interception environments

2021-09-17 Thread Andreas Weigel
Hi, I noticed that squid behaves differently with regard to checking the SNI of a (fake-)Connect request depending on the sslbump step a "splice" is performed. This is more or less a follow-up on " Squid spliced TLS handshake failing with chrome/ium fallback for certain servers". If spl
