   2 //  cleaner HTTP header test infrastructure
   3 //
   4 //  tests bugs:  589292, [add more here: see hg log for definitive list]
   5 //
   6 //  TO ADD NEW TESTS:
   7 //  1) Increment up 'lastTest' to new number (say, "99")
   8 //  2) Add new test 'handler99' and 'completeTest99' functions.
   9 //  3) If your test should fail the necko channel, set
  10 //     test_flags[99] = CL_EXPECT_FAILURE.
  11 //
  12 // TO DEBUG JUST ONE TEST: temporarily change firstTest and lastTest to equal
  13 //                         the test # you're interested in.
  14 //
  15 //  For tests that need duplicate copies of headers to be sent, see
  16 //  test_duplicate_headers.js
