Mediawiki should use the HTTP_HOST instead of SERVER_NAME, if the first one is set.
Problem: Using a tcp-forward HTTP-redirect do not work because the server name
included in the Location header is set based on the local settings of the
webserver. However, the name of the reversed proxy should be used. This one is
provided in the HTTP-"Host:"-header, if HTTP 1.1 is used.
