What is App Pool and App Domain? What is the difference
between the two.
Answer Posted / vinodh.m
An application pool is a group of one or more URLs of
different Web applications and Web sites. Any Web directory
or virtual directory can be assigned to an application pool.
Every application within an application pool shares the same
worker process executable, W3wp.exe, the worker process that
services one application pool is separated from the worker
process that services another [Like starting MS Word and
opening many word documents]. Each separate worker process
provides a process boundary so that when an application is
assigned to one application pool, problems in other
application pools do not affect the application. This
ensures that if a worker process fails, it does not affect
the applications running in other application pools. [i.e]
for Eg., If word document is having issue it should not
logically affect your Excel Sheet isn’t it.
application domain is a mechanism (similar to a process in
an operating system) used to isolate executed software
applications from one another so that they do not affect
each other. [i.e] opening of MS WORD doesn’t affect MS EXCEL
you can open and close both the applications any time since
there is no dependency between the applications. Each
application domain has its own virtual address space which
scopes the resources for the application domain using that
address space.
