How to divert the traffic to targer servers withou

问题:

I have 4 web servers, These web servers hosts nearly 8 different websites. I am planning to use path based routing like http://myexample.com/website1/..

For example when i deployed by application on port 8580 and create the path based rule in ALB.. and hit the url it is not working. Instead i had to use http://myexample.com:8580/website1.

Please help to resolve this, how can i remove the port number from URL.

Since all these are internal application under single domain. I do not have an option of using different domain names or different load balances.

The reason is your load balancer listening on the same port which is used in the webserver.

You need to define a listener for LB to listen on a port and forward traffic to target on the desired group.

specify port 8580 in the target group and specify 80 in the Loadbalancer listener.

Update:

If all application running on the same instance you need host-based routing.

In the above screenshot, suppose behind each target group there is one instance, but five different target group so api.example.com will route to its own target group.
