Yes, this happens during SslBump step1 as described at

According to the above wiki page (and my understanding of how SslBump
should work), Squid should make another adaptation pass during step2.
You may want to make sure that your Squid does not discover some error
_before_ it can start doing eCAP during step2.
If your eCAP service does not see the second CONNECT (during step2), I
suggest using the latest Squid v4 with the following "minimal" SslBump
ssl_bump peek step1
ssl_bump splice all
Does the above work without problems when eCAP is turned off?
Does the above deliver the second CONNECT to eCAP when it is enabled?

We should not be discussing code details on squid-users, but the latest
Squid v4 does not have that function AFAICT:
