Hi folks,
I'm wanting to do the following thing:
1. User browses for an image
2. User crops image with a pre-set sized outline
3. Image is uploaded onto the server
I know how to do #1 and #3. I also know how to do the
error checking stuff like making sure the file/image
is the right size, etc.
In PHP I use something like this:
$isAjaxCall = isset($_SERVER['HTTP_X_REQUESTED_WITH']) &&
$_SERVER ['HTTP_X_REQUESTED_WITH'] == 'XMLHttpRequest';
I'm not a ColdFusion developer, but it looks like CF's
GetHttpRequestData can give you this information.

Isn't that what you do with this code is your
