/*
 * TestSever customized specifically for the needs of:
 * Bug 1111834 - sendBeacon() should not follow 30x redirect after preflight
 *
 * Here is a sequence of the test:
 * [1] preflight channel (identified by the queryString 'beacon' and method 'OPTIONS')
 * [2] actual channel (identified by the queryString 'beacon') which gets redirected
 * [3] should never happen (the actual redirected request)
 * [4] xhr request (identified by the queryString 'verifyRedirectDidNotSucceed')
 *     which checks if the state was not changed from 'green' to 'red'. If the channel
 *     woulnd't be blocked correctly the redirected channel would set the state to 'red'.
 *
