Using a single file as a template for th whole site

Question

My Application.cfm file has the code that i am using as a
template for the rest of my site. On the template, the title
section looks like this. <cfif
IsDefined('pagetitle')><cfoutput><title>#pagetitle#</title></cfoutput><else><title>Welcom e</title>
and the title variable is set on the end page. lets just say
test.cfm but when i view test.cfm the title is always Welcome. How
can i fix this. and this also goes along with my content. On the
application.cfm pge i have empty divs. on the test.cfm page i have
the same divs only with all the page-relevant information in them,
but they never show up. I know that this is how you do it in php.
but how do you do it in ColdFusion

Theres a few things you could do here... none of which I
think is the perfect solution. It all depends on your preference as
well as the needs of your application.
-- Move your page title code to another file - call it
Header.cfm or something along those lines -- and include it in
every page after you set the pagetitle variable.
-- Use Javascript to add the page title to some div at the
top of the page when it loads. (not my favorite option here)
-- Check out the CF tag cfsavecontent. You could save the
generated HTML in test.cfm into a variable and output it later. Put
your pagetitle code in OnRequestEnd.cfm, which is called AFTER
every template is executed. Set your pagetitle variable in test.cfm
and save the HTML into a variable, then in OnRequestEnd.cfm output
the pagetitle followed by your generated content.
