No. Once you run get countries, the query, then:
<cfset application.countries = getcountries>
<cfoutput query="application.countries">
is just like calling
<cfoutput query="getcountries">
Except the entire recordset from the getcountries query is in memory
in the application.countries variable.
The application scope is identical to the session scope, except:
Session scope variables are only available to the user that set them
under the application name set in the cfapplication tag, based on the
user's cfid and cftoken.
Application scope variables are available to everyone under the
application name as set in the cfapplication tag.
I'm relatively sure you can store any complex structure in session
and application variables. With client variables, anything other than
simple strings must be serialized with WDDX.
You can also update the data available in the variable by different means.
