Intercept all HTTP requests to the server

One: intercepts all HTTP requests to the server.

Add in config,

<system.webserver><modules><add name="httpauthvalid " type= " ygpt. Country.Auth.HttpAuthvalid"/></modules></system.webserver>

Then each HTTP request is advanced by this class (this class needs to inherit

System.Web.IHttpModule

）
