 // Test that verifies that a cross-process transfer doesn't lose session
 // history state - https://crbug.com/613004.
 //
 // Trigerring a cross-process transfer via embedded_test_server requires use of
 // a HTTP redirect response (to preserve port number).  Therefore the test ends
 // up accidentally testing redirection logic as well - in particular, the test
 // uses 307 (rather than 302) redirect to preserve the body of HTTP POST across
 // redirects (as mandated by https://tools.ietf.org/html/rfc7231#section-6.4.7).
