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

var firstTest = 1;   // set to test of interest when debugging
var lastTest = 4;    // set to test of interest when debugging
