Asp.net page execution [asp.net architecture]

Server system required 2 things for asp.net

1. IIS installation

2. net installation

.net installation will configure IIS with a library called aspnet_isapi.dll (internet server application programming interface)

Whenever the first request comes to the webserver. Server will forward asp.net page request to asp.net worker process using aspnet_isapi.dll

Ø  Asp.net worker process can be called as asp.net run time it will make use .net services to process asp.net page

Ø  Asp.net worker process will compile asp.net page into complied code in the form of DLL file, this complied will be serving the different client request, this makes execution faster & provides better performance.

Location of webpage dll with in server system->

C:\windows\microsoft.net \framework\version\temporaryasp.net files\
