I don't understand this all that well. I'll say this in my own words and if
this is what you need, I think I have a possible solution.
User scenario:
Johnny Foo clicks on a link that points to http://server/directory/page1.cfm
CF server processes page1.cfm and in the process, creates a JavaScript
variable.
Web server sends resulting page back
Johnny Foo receives a page1.cfm in HTML format, and because it contains
Javascript, it will be executed, computing a variable.
Then...
Scenario 1a
You would like to call http://server/directory/page2.cfm?variable=1 without
Johnny knowing it, and without changing the page.
Solution: I have a trick to do that.
or
Scenario 1b
You would like to call http://server/directory/page2.cfm?variable=1 and then
have Johnny receive page2.cfm in HTML format.
use
window.location =
'http://server/directory/page2.cfm?variable='+jsvariable
after you compute jsvariable. Make sure page1.cfm has no HTML output. The
user will see a white page for a second. Or put a nice short message in
page1 that will, at best, flash momentarily.
