Allowable File Name Extensions

If you have chosen to lock down your IIS by removing the default Allow unlisted file name extensions setting, then you must add certain extensions to the allowable list by doing the following:

1. In the Connections pane, open the Sites node under the server name. Click the XFRACAS site.
2. In the Home page, double-click Request Filtering.
3. For each of the following extensions, in the Actions area, click Allow File Name Extension and enter the extension:

.asax	.dtd	.js
.ashx	.gif	.png
.aspx	.htm	.xml
.axd	.html	.xslt
.css	.ico
