Answer / aslam

In Proc mode is usefull for small application which can be
hosted on single server. This mode is most common and
default method to store session information. session data
is stored in memory of local web server. it is not ideal
for web farms and web gardens
Out of proc mode is ideal for scalable and highly
avialble application. it supports web farm and web gardens.
session state is held in process called aspnet_state.exe
that runs as a windows service.

Answer / tanveer

web Application is statless ,no state is maintained between
browser ans server , many ways are there to maintain state
on server or/and clent ,session is one of the most
important object to maintain state on server side .
Session can be stored on three different physical space,
1)on the same location were the application run i.e. in the
same process in worker process. which is known as inproc
In which form authentication can work and session_end
function does work in global.asax file.

inproc is the fastest way ,
but it gets referesh when iis recycle or restarted and data
lost.

2) out proc is the another way to store session on another
location (server) .
