You need NGNIX or Apache HTTP server as a proxy server for forwarding http requests to appropriate application -> which listens particular port (or do it with CNAME which provides Hosting company). It is most powerful solution and this is just a really easy way to keep adding new subdomains, or to add new domains automatically when DNS records are pointed at the server.

Apache era call it Virtual host -> httpd.apache.org/docs/trunk/vhosts/examples.html
NGINX -> Server Block https://www.nginx.com/resources/wiki/start/topics/examples/server_blocks/

The hosts file is for host name resolution only  on Windows as well as on Unix-like systems   You cannot put port numbers in there  and there is no way to do what you want with generic OS-level configuration - the browser is what selects the port to choose   So use bookmarks or something like that   Some firewall routing software might allow outbound port redirection  but that doesn t really sound like an appealing option for this

I managed to achieve this by using Windows included Networking tool netsh    As Mat points out   The hosts file is for host name resolution only  so a combination of the two did the trick for me   Example    Overview  example app 80                               lt --Link by Hosts File   -- gt  127 65 43 21 80                               lt --Link by netsh Utility         -- gt  localhost 8081   Actions   Started my server on localhost 8081 Added my  local DNS  in the hosts file as a new line   127 65 43 21     example app   Any free address in the network 127 0 0 0 8  127 x x x  can be used  Note  I am assuming 127 65 43 21 80 is not occupied by another service  You can check with netstat -a -n -p TCP   grep  LISTENING    added the following network configuration with netsh command utility   netsh interface portproxy add v4tov4 listenport 80 listenaddress 127 65 43 21 connectport 8081 connectaddress 127 0 0 1  I can now access the server at http   example app   Notes   - These commands file modifications need to be executed with Admin rights  - netsh portproxy needs ipv6 libraries even only to use v4tov4  typically they will also be included by default  otherwise install them using the following command  netsh interface ipv6 install    You can see the entry you have added with the command   netsh interface portproxy show v4tov4  You can remove the entry with the following command   netsh interface portproxy delete v4tov4 listenport 80 listenaddress 127 65 43 21    Links to Resources    Using Netsh Netsh commands for Interface IP Netsh commands for Interface Portproxy Windows Port Forwarding Example

The simplest way is using Ergo as your reverse proxy  https   github com cristianoliveira ergo  You set your services and its IP PORT and ergo routes it for you      You can achieve the same using nginx or apache but you will need to configure them

If what is happening is that you have another server running on localhost and you want to give this new server a different local hostname like  http   teamviewer   I think that what you are actually looking for is Virtual Hosts functionality  I use Apache so I do not know how other web daemons support this  Maybe it is called Alias  Here is the Apache documentation   Apache Virtual Hosts examples

Using netsh with connectaddress 127 0 0 1 did not work for me   Despite looking everywhere on the internet I could not find the solution which solved this for me  which was to use connectaddress 127 x x x  i e  any 127  ipv4 address  just not 127 0 0 1  as this appears to link back to localhost just the same but without the restriction  so that the loopback works in netsh

This doesn t give the requested result exactly  however  for what I was doing  I was not fussed with adding the port into the URL within a browser  I added the domain name to the hosts file 127 0 0 1      example com  Ran my HTTP server from the domain name on port 8080 php -S example com 8080  Then accessed the website through port 8080 http   example com 8080  Just wanted to share in case anyone else is in a similar situation
