Since the cache_peer config I gave you earlier did not help I'm afraid 
there is nothing else just involving config that will work either for 
that Squid version.

Your options are now to try a more recent Squid. Up to and including the 
Squid-5 latest development code.

If none of the newer code either works right away, or with the config I 
gave then your options are further decreased to hacking around on the 
code to figure out what is going on. Christos Tsantilas 
(<https://wiki.squid-cache.org/ChristosTsantilas>) is the main developer 
working on SSL-Bump, for assistance with code-level stuff a mail to 
squid-dev mailing list would be best.


Sorry that I cannot be of more help on this. I'm very interested in 
finding out what is going wrong for your use-case though - it should be 
working for sibling proxies.
