Exact, and it is a pretty good idea ;-)

As is XMLHttpRequest.
All the solutions mentioned so far (xmlHTTPRequest, iFrame and an image) are
all HTTP requests. They all have the overhead of
Personally I find using an image the most reliable for the task at hand
I totally agree, and which page doesn't need an image anyway?, So there
is actually NO overhead at all, except for the extra characters for the
screen resolution, which is not even worth to talk about.
Brilliant idea
why not just write it to cf variables at the top of the page from JS?

I know how to do it with javascript but I would need it in a
coldfusion variable
without reloading the page.
CF has no mean to know the screen resolution. Since you know how to do it in JS,
get the values in the first page and transmit it to the next in a form or URL
value,
then store them in

? Please elaborate? Javascript runs on the browser, CF on the server.
The only way for JS to write stuff to CF variables is to do some sort of
post back to the server...

That's right.
You could do a post to a page that doesn't return content (via a no-content
header), but you can't get it into the current CF
I've got code and explanation of this here:

The server call is actually done (via client-script) as an image so you can
get the res into CF on one page (but can't, of course, do anything with

This is where an AJAX type application might work wonders. As soon as
you load the page, do a XMLHttpRequest and send
that's similar to what the link I posted does, but with an image.
Exact, and it is a pretty good idea ;-)

Screen resolution info and other CLIENT-related variables can only be
obtained via JavaScript.
Since CF is a SERVER-side application, it has no way to obtain or use
client side information unless it uses JavaScript.

Create a page that has some javascript that automatically redirects to a second page
with the resolution embedded in the URL string.

Hi everyone,
Does anyone know of a CF way to determine the users screen resolution? I
know about using JS to produce
SCRIPT language="JavaScript" type="text/javascript"
function getscreen(width,height) {
document.write('form name=form1 action=index2.cfm method=post');
document.write('input type=hidden name=width value=' + width + '');
document.write('input type=hidden name=height value=' + height + '');
BrowserHawk is an excellent tool I've used as javascript and he has it as a
CF tag as well as for ASP.
Here's some links:
