Nginx Redirect subdomain to a folder but keep the link on browser

Hi

On a domain domain.com i have a folder inside named /knowledgebase/ and i create a sub domain kb.domain.com that i want to point to this folder on the main vhost account but to keep the subdomain on the browser for the user.

Just to display the content from this folder from the main domain....

How can i do that?

I was think to adjust the config for the sub domain but i am not sure how to do it

Code:

#server {
#  listen  80;
#  server_name kb.domain.com;
#  return 301 $scheme://www.kb.domain.com$request_uri;
#  }

server {
  server_name kb.domain.com www.kb.domain.com;
  

I was try also:

Code:

location /home/nginx/domains/domain.com/public/knowledgebase {

And point the subdomain to main domain path but was not working....

---

 

Ops sorry i was set location and not root path

Checking now....

 

Yes now is working great and i can see the content from this folder

But on the browser is redirecting to main domain.com and not keep the subdomain

Is there anyway to keep the subdomain on browser ?
