Is there any way to resolve domain to another domain with port?
we know we can use CNAME to implement: access domain then resolve to a special domain like below:
domain1.com -> demo.com
domain2.com -> demo.com
domain3.com -> demo.com
but is there any way to implement resolve to a domain with port?
domain1.com -> demo.com:3201
domain2.com -> demo.com:3202
domain3.com -> demo.com:3203
EDIT:
I know use 302 can redirect to the special URL, but the domain in browser will change. is there any better way to implement it?
The only way to do what you ask is to use a reverse proxy to hide the “origin” server.
Essentially, you have a server listening on domain1.com and it forwards the traffic to demo.com:3201.
DNS cannot do what you ask.
