For any error generated by the reverse proxy at Tor's end, need to create a custom error
page detailing useful information (for example, where we block _tor2web_ it'd be helpful
to explain why the request has been blocked).

Have configured a basic notification page for tor2web pages, but because NGinx is being a
pain, it doesn't really return an appropriate status code. Currently it'll 301 the visitor
to a page called 405.html which details why the request was blocked.

For some reason, NGinx seems to be quite determined not to use custom error pages for
405/406 etc, will come back and look at sorting that out later. For now the config in
place is

-- BEGIN SNIPPET --


    error_page 405 = /405.html; # This has no impact currently
    location /405.html {
        root /usr/share/nginx/onions/bentaskercouk;
    }

    if ($http_x_tor2web){
        set $tor2web T;
    }


    # Avoid redirect loops
    if ($request_uri = '/405.html'){
        set $tor2web R;
    }

    if ($tor2web = T){
        return 301 /405.html;
    }

 -- END SNIPPET --
