Hi, We've running nginx as reverse proxy for backend domain named "mydomain.com". On proxy server we've setup vhost that covers domain and all subdomains *. mydomain.com.
What we need is that if user request to any subdomain like work.mydomain.com, he should be proxied to single backend mydomain.com but all underline links e.g css/js should be changed to *work-mydomain-com.newdomain.com <http://work-mydomain-com.newdomain.com>* . If second user requests nginx.mydomain.com, he should be proxied back to single backend *mydomain.com <http://mydomain.com>* while underline links css/js should be changed to *nginx-mydomain-com.newdomain.com <http://nginx-mydomain-com.newdomain.com>.* As you can see we want all dots in domain/subdomain to be changed to hyphen (-). I am able to change css/js links using sub_filter to work.mydomain.com.newdomain.com by making use of $host param but i am struggling on changing it to hyphens. Please check this nginx config and advise on how to change hostname from dots to hyphen in sub_filter e.g: mydomain.com ==> mydomain-com.newdomain.com work.mydomain.com ==> work-mydomain-com.newdomain.com nginx.mydomain.com ==> nginx-mydomain-com.newdomain.com ==================================================== upstream server { server 10.10.10.10:443; } server { listen 80; listen 443 ssl http2; ssl_certificate /etc/ssl/certs/mydomain/mydomain.crt; ssl_certificate_key /etc/ssl/certs/mydomain/privkey1.pem; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_ciphers 'ECDHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-GCM-SHA256:DHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES256-GCM-SHA384:AES128-GCM-SHA256:AES256-SHA256:AES128-SHA256:AES256-SHA:AES128-SHA:DES-CBC3-SHA:HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4'; ssl_prefer_server_ciphers on; server_name mydomain.com *.mydomain.com; location / { proxy_set_header Accept-Encoding ""; #subs_filter_types text/css text/xml text/css; sub_filter "https://mydomain.com"; "https://$host.newdomain.com";; sub_filter_once off; proxy_pass https://server; proxy_set_header HOST mydomain.com; } }
