In the latest Squids, the above config probably does not do what you
want. For nobumpSites, your config is equivalent to:

  ssl_bump peek step1
  ssl_bump peek step2
  ssl_bump bump step3

which does not work in most cases -- you cannot bump after peeking at step2.

For all other sites, you config is equivalent to:

  ssl_bump peek step1
  ssl_bump bump step2

which works.

If you want to bump everything, then this should work:

  ssl_bump stare all
  ssl_bump bump all

If you want to bump everything other than nobumpSites (which needs SNI),
then start with something like this:

  ssl_bump peek step1
  ssl_bump splice nobumpSites
  ssl_bump bump all
