ISAPI dll supports in handling the .aspx page request.

When the IIS process (inetinfo.exe) receives an HTTP request, it uses the filename extension of the requested resource to determine which ISAPI program to run to process the request. When the request is for an ASP.NET page (.aspx file), IIS passes the request to the ISAPI DLL capable of handling the request for ASP.NET pages, which is aspnet_isapi.dll.
