Artifactory remove /api/gems/gems from url with nginx - nginx

Question

I have an Artifactory server as a gem repository. In order to use the local server I need to setup my gem sources with this ugly url.
gem source -a gems.example.com/api/gems/gems/
I'd like to remove the need for developers to know the URI /api/gems/gems/ so they can simply access gems.example.com
server {
listen *:443 ssl default;
server_name artifactory.example.com gems.example.com;
ssl on;
ssl_certificate /etc/ssl/certs/artifactory.example.com.crt.pem;
ssl_certificate_key /etc/ssl/private/artifactory.example.com.key.pem;
location / {
if ( $request_uri ~ ^/(.*)$ ) { proxy_pass http://localhost:8081/artifactory/$1; }
proxy_cookie_path ~*^/.* /;
proxy_pass http://localhost:8081/artifactory/;
proxy_pass_header Server;
proxy_read_timeout 2400s;
}
A rewrite would work, however the nginx configs already have the following if, and nginx does not allow for multiple conditionals.
not valid:
if ( $request_uri ~ ^/(.*)$ && $server_name) { proxy_pass http://localhost:8081/artifactory/$1; }
How can I eliminate /api/gems/gems/ from the url https://gems.example.com/api/gems/gems/ ?

Use multiple server blocks like so:
Note that the second server block has the following changes.
- server_name
- no 'default' on the listen line
- proxy_pass http://localhost:8081/artifactory/api/gems/gems/
/etc/nginx/sites-enabled/artifactory.conf
server {
listen *:443 ssl default;
server_name artifactory.example.com;
ssl on;
ssl_certificate /etc/ssl/certs/artifactory.example.com.crt.pem;
ssl_certificate_key /etc/ssl/private/artifactory.example.com.key.pem;
location / {
if ( $request_uri ~ ^/(.*)$ ) { proxy_pass http://localhost:8081/artifactory/$1; }
proxy_cookie_path ~*^/.* /;
proxy_pass http://localhost:8081/artifactory/;
proxy_pass_header Server;
proxy_read_timeout 2400s;
}
# ....
/etc/nginx/sites-enabled/artifactory-gems.conf
server {
listen *:443 ssl;
server_name gems.example.com;
ssl on;
ssl_certificate /etc/ssl/certs/artifactory.example.com.crt.pem;
ssl_certificate_key /etc/ssl/private/artifactory.example.com.key.pem;
location / {
if ( $request_uri ~ ^/(.*)$ ) { proxy_pass http://localhost:8081/artifactory/api/gems/gems/$1; }
proxy_cookie_path ~*^/.* /;
proxy_pass http://localhost:8081/artifactory/api/gems/gems/;
proxy_pass_header Server;
proxy_read_timeout 2400s;
}
# ....
Note /gems/gems corresponds to the virtual repo on artifactory called 'gems'. If you have multiple gem repositories, you will need to add a vhost for every repo.
