Rewriting location header field
-------------------------------
nghttpx automatically rewrites location response header field if the
following all conditions satisfy:
* URI in location header field is not absolute URI or is not https URI.
* URI in location header field includes non empty host component.
* host (without port) in URI in location header field must match the
host appearing in :authority or host header field.
When rewrite happens, URI scheme and port are replaced with the ones
used in frontend, and host is replaced with which appears in
:authority or host request header field. :authority header field has
precedence. If the above conditions are not met with the host value
in :authority header field, rewrite is retried with the value in host
header field.
