From what I understand, request is just like any local variables scope.
<cfset variables.dns = "mydatasource">
<cfset attributes.dns = "mydatasource">
<cfset request.dns = "mydatasource">
The difference being, if you need to access the first 2 inside of a
custom tag, you'd have to pass it into the tag then access it with
the attributes scope.
<cf_mytag dsn = #variable.dns#>
or
<cf_mytag dsn = #attributes.dns#>
The inside the custom tag:
<cfquery name="myquery" datasource="#attributes.dns#">
Where with the request variable, you could access it directly.
<cf_mytag>
Then inside:
<cfquery name="myquery" datasource="#request.dns#">
Of course, it's not limited to datasource names. Any variable that
you set outside the tag that you need to access inside the tag can be
accessed directly without referencing them in the caller tag if you
set them with the request scope.
