Nope. 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

Nope again, I'm afraid it doesn't (see further down)

*oops* thank you all for the hint! 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 "<base href=\"".esc_url($base_url)."\" />\n";
}
print "<!--
$base_url
$my_url
$my_uri
-->";
