Difference Between Integrated Authentication and Classic Authentication types in IIS

I Am providing this article to brief the differences between classic and integrated methods. This is a question we get in our minds. Here is the answer below.

Classic   Users: 

1.     The incoming HTTP request is received through the IIS core.

2.     The request is processed through ISAPI.

3.     The request is processed through ASP.NET.

4.     The request passes back through ISAPI.

5.     The request passes back through the IIS core where the HTTP response finally is delivered

integrated uses:

1.     The incoming HTTP request is received through the IIS core and ASP.NET.

2.     The appropriate handler executes the request and delivers the HTTP response.
