Reverse proxy works like this: - a "public" apache VirtualHost receives an http(s) request for a certain URL /a/b/c... and has the location /a/.* configured as a revProxy location - the public vhost repeats that request to the revProxy target - the revProxy target receives a request from the "public" vhost and serves it as usual (this is were the gitweb.cgi script actually is run, only seeing the request made by the public vhost, not the initially requesting client, thus all information about the publicly visible git URI is lost and never gets passed on to gitweb.cgi) - the public vhost receives the response and forwards it to the client, pretending he himself had answered the request >> Lacking that, a plain >> >> our $base_url = 'whatever'; >> >> in the gitweb config should probably work Nope again, I'm afraid it doesn't (see further down) > See also gitweb/README, the "Gitweb config file variables" section: > > * $base_url > Base URL for relative URLs in pages generated by gitweb, > (e.g. $logo, $favicon, @stylesheets if they are relative URLs), > needed and used only for URLs with nonempty PATH_INFO via > .

I totally missed that. However, I just tried that and it failed. $base_url gets ignored in gitweb.conf and even setting $my_url and $my_uri in gitweb.conf seems to have no effect at all. For testing purposes I printed the relevant variables to the html header: gitweb.conf: ************ our $feature{'pathinfo'}{'default'} = [1]; our $base_url = "https://foobar"; our $my_url = "https://foo"; our $my_uri = "https://bar"; ************ gitweb.cgi:3424 ************ # the stylesheet, favicon etc urls won't work correctly with path_info # unless we set the appropriate base URL if ($ENV{'PATH_INFO'}) { print "\n"; } print ""; ************ - git repo listing public url: https://sb74/projects/gitweb revProxy url: https://localhost:446/projects/gitweb ************ localhost Git ************ - git summary of repo "test1" public url: https://sb74/projects/gitweb/test1/summary revProxy url: https://localhost:446/projects/gitweb/test1/summary ************ localhost Git - test1/summary ************ Any ideas?
