Tips for swapping hosts in Postman and JavaScript

Is there a simple way to allow the front-end and testing teams to easily override the host header to match {tenant}.mydomain.com while working locally? I'm looking for a solution that doesn't involve constant changes. Any ideas on how I can achieve this? Below is my .net 7 code for checking the host:

var host = Request.Host.Value;
        if (string.IsNullOrEmpty(host))
        {
            return BadRequest("Missing host header.");
        }

I've come across suggestions to use the hosts file, but it seems like a rigid solution that would need adjustments every time we want to test a different tenant.

Environments in Postman serve a specific purpose.

It is recommended to set up distinct environments for each host header.

Every environment should include a variable representing the actual host header.

Assuming we are discussing host headers according to this explanation.

Understanding the HTTP "Host" header

In this case, you should add a header named host (without modifying the URL).

Instructions for adding a header in Postman can be accessed here.

Instead of inputting a fixed value, utilize the environment variable. For instance, {{hostHeader}}.

The tester simply needs to adjust the environment to correspond with the desired host header.

If the intention is to change the host in the URL, the same approach applies. Set up environments and create a variable for the {{baseURL}} utilized in the request.
