Application.cfm or Application.cfc

[jeby]

I am trying to get more information on the differences between using an
Application.cfm or an Application.cfc file. I think that the main difference
is that the .cfm is a tag based where .cfc is script based? I have no idea if
that is correct....just what i think i have picked up.

Please reply with your opinions and preferences as well as an explanation of
what the differences are and the advantages of each.

I am beginning to write an application for the company I work for and am
trying to make sure i am taking the right approach. Thanks for all of your
help!

No you are wrong. You can use tags in either just like you can use cfscript in
either.

Application.cfc replaces the use of Application.cfm and OnRequestEnd.cfm and
adds new abilities.

Application.cfm very similar to a cfinclude that is run on every page request
before any other code, where as Application.cfc is a ColdFusion Component. It
has variaous methods that are called in different situations. You have
onRequestStart() and onRequest() which are called before every page. You also
have onSessionStart() and onSessionEnd() methods that are self explainatory.

You should read

wwhelp.htm?context=ColdFusion_Documentation&file=0 0001117.htm and read through
the following pages by using the right arrow at the top.

Ok. Application.cfc definatly sounds like the way I need to go. Does the
Application.cfc file also go in the root like the Application.cfm?

Are you able to get session information during the onSessionStart() and
onSessionEnd() such as SessionID and Username of the person that was is the
session is their username was a session var such as Session.Username?

I want to keep track of all of the current sessions in my application. I want
to be able to display a list of users that have current sessions. Is that
possible?

Well, onSessionStart() would only be called the first time a user browses to
your site -- they just started a new session. Using onRequestStart() will let
you do things at the beginning of every page load, which is what it sounds like
you want to do.
