redirect - Nginx: dynamic proxy from url to subdomain -

i'm trying write nginx conf dynamically redirect url webapp, based on uri. use proxypass directive. example, want redirect http://www.example.com/clientname/ http://clientname.internaldomain.local/webapp

so far, succeded replacing new host, uri broken because can't split it. (now can't replace host, dunno why ...)

here actual non working conf:

    server {        resolver 192.168.137.71;        listen   80;        server_name     tomservpa1;      location  ~ (^\/(.*)\/) {                  set $ccehost $2;                 proxy_set_header        x-forwarded-for $proxy_add_x_forwarded_for;                 proxy_set_header        x-forwarded-host $host;                 proxy_set_header        x-forwarded-server $host;                 proxy_set_header        x-real-ip $remote_addr;                 proxy_pass              http://$ccehost.internaldomain.local:9780/webapp/$new_request_uri;                 proxy_redirect          off;                 proxy_set_header        host $host;         }  } 

did ?

thanks.

you can use named captures in location directive avoid scope , ambiguity issues. example:

location ~ ^/(?<ccehost>[^/]+)/(?<new_request_uri>.*)$ {     rewrite ^ /webapp/$new_request_uri break;     ...     proxy_pass http://$ccehost.internaldomain.local:9780;     ... }
