Depends. There are many possibilities.

TLS requires that the HTTP messages are encrypted every time they travel
over a network connection. That includes when sending over connections
between two proxies. Even when sharing a certificate they would still
encode/decode twice.

Bumping twice is actually the *ideal* situation.

Sending to a cache_peer eliminates the ability of Squid's mimic feature
to help protect against as-yet undiscovered TLS and certificate issues
on origin servers.
