Round trips to the server

[Guest_imported]

Hi
I'm having trouble understanding life cycle of an application.
All the code-behind files are compiled into a single .dll file.The first time a user browses to the .aspx page, ASP.NET automatically generates a .NET class file that represents the page, and compiles it to a second .dll file. The generated class for the .aspx page inherits from the code-behind class that was compiled into the project .dll
file.This I know.But

---is this page's .dll file created everytime user sends request or does it exist for as long as app is running

---When user makes first request app starts running and ends only when Global.asax file is edited.But what is application here?
This .dll file that represents a single page or is it
code-behind .dll file or something else?

---I also can't see why ASP.NET is faster than ASP,since page is initialized, processed and disposed of every time a round trip to the server occurs.

I'm grateful for your help

1st Question:
The second dll is created only at the first request.

2nd Question:
the dll contains all the code behind and all the other non aspx files of your project. In the dll the language used is MIL. This gives the ability to the browser and server to compile the remaining part when the user requests a specific function or event and the JIT compiler (Just In Time) while compile only the code that manages that function or event.
This answers also the third question.

The first time a page is viewed, the compiled has to do some extra work and prepares the JIT compiler. After that, all the requests are faster.

hope this clears up =)

I really apologize if I'm going to sound stupid,but I still don't completly get it.

-So if you have 10 aspx files in a project and there is a request to each one of them,then 10 .dll files will be runing until the app ends?

-So when a new request comes for the second or third time,the MSIL code of this .dll representing a page gets chanded only where it needs to be changed and the rest of MSIL code stays the same?

Thanks a lot

Q) -So if you have 10 aspx files in a project and there is a request to each one of them,then 10 .dll files will be runing until the app ends?
A) -Yes all the 10 .dll files will be running but will be running untill the response is sent back to the clients.

Now I'm even more puzzled.Mr.Alcar said that the second .dll is created only at the FIRST request so I figured this .dll runs until app ends?Anyone?

Thank you for helping me
