When I try using proxy_pass within location ~ something I get :
: "proxy_pass" may not have URI part in location given by regular expression, or inside named location, or inside the "if" statement, or inside the "limit_except" block in /etc/nginx/nginx.conf:52

the line is proxy_pass http://127.0.0.1:8080/;

Do you have an idea what the problem might be?

Thanks,
Ivo
