Question

Is there a way to accept any hostheader with ASP.Net WebApi eg:

var config = new HttpSelfHostConfiguration(http://*:8080);

which I would expect to accept any host header

Answer 1

Webapi appears to accept any host header (domain) for a self hosted service. For example if you bind

var config = new HttpSelfHostConfiguration(http://zzz:8080);

webapi will accept calls from

http://aaa:8080 (assuming dns is pointing to the machine)

or

http://localhost:8080

This is not terribly intuitive
