How to setup nopCommerce Multi-Store on Shared Hosting and Localhost(IIS Express)

I am using nopCommerce 3.80


Please help me!!

Use HOSTS file

I've been tried

hosts file:
127.0.0.1 testhost1
127.0.0.1 testhost2

HOST values:
The first store : testhost1:15536
The second store : testhost2:15536

When run on the browser: http://testhost1:15536/ or http://testhost2:15536/, the error :

Bad Request - Invalid Hostname

HTTP Error 400. The request hostname is invalid.

Is 15536 your port #?  (15536 was just an example)
