Dynamicweb has a nice image handler for manipulating images on the fly (Admin/Public/GetImage.ashx). But how do I limit the use of this handler to only allow a predefined set of values?
The reason I ask this is because someone who want to do harm, could easily write a script that continuously requests different large resolutions. This would result in a very high CPU load and since the images are also being cache on the disk, the disk-space would run out pretty fast too,
