<title> Bug 1706126: Test https-first, downgrade first request and then upgrade redirection to subdomain</title>

/*

 * Description of the test:

 * First we request http://redirect-example.com which HTTPS-First upgrades to https://redirect-example.com.

 * The request https://redirect-example.com doesn't receive an answer (timeout), so we send a background

 * request.

 * The background request receives an answer. So the request https://redirect-example.com gets downgraded

 * to http://redirect-example.com by the exempt flag on the loadinfo.

 * The request http://redirect-example.com gets redirected to http://wwww.redirect-example.com. At that stage

 * HTTPS-First should clear the exempt flag and upgrade the redirection to https://wwww.redirect-example.com.
