Building Intelligent sessions into your framework |
||||||||
Have you ever been logged into an application and had your session timeout, then when you log back in you are returned to a different place altogether?
This article deals with a way to mark where a user was in your application and return them to that location when they log back in. It also allows a user to deep link into an application.

ImageCFC losing file permissions on image manipulation |
||||||||
This article deals with a work around for a problem I had been experiencing with the imageCFC ( http://www.opensourcecf.com/imagecfc/ ) open source project. When resizing an image the file permissions were being lost on the edited file. This meant that the server operating system could not read or serve up the file to the browser.
I've been using imageCFC as I have a variety of coldfusion server versions (7 and 8), and I like the fact that in the resize method you can specify the maximum size for the width and height, and it will resize down to that size, and keep the aspect ratio of width-to-height.
