tgpfeiffer / HostAndPath.scala
Created Jun 6, 2013
A replacement for S.hostAndPath that takes into account Lift running on a host with a different port and SSL setting than the reverse proxy in front of it.
View HostAndPath.scala
def realHostAndPath(forceNoSsl: Boolean = false): String =
S.request.flatMap(req => (Box !! req.request).map(r => {
// X-Forwarded-Host contains host *and* port (if not standard)
r.header("X-Forwarded-Host") match {
case Full(hostAndPort) =>

case "http" if r.header("X-SSL").isDefined =>
"https://" + hostAndPort + S.contextPath

// this (correct) URL is not liked well by Java applets, so we allow to override it
