Recently I had a PCI compliance scan run on a Kentico website and it showed DOS vulnerability on the site when this URL was accessed: http://www.mywebsite.com/AUX/.aspx.

I'm wondering what affect adding this to my web.config

<httpRuntime relaxedUrlToFileSystemMapping="true"/>

might have on Kentico. I found an article explaining reserved file names here.

Will it cause URL rewrite problems? Problems with MVC (not used in the site that I'm aware of).
