Enable AllowDotInPath in UrlScan

By default, UrlScan denies access to any URLs which include a dot in the path, so any user uploaded content in these paths is inaccessible.

To resolve this issue, take the following steps:

1. Open urlscan.ini.

2. Find the line that reads:

   AllowDotInPath=0

3. Change this to:

   AllowDotInPath=1

4. Save and close the file.

5. If you're using versions prior to IIS7, you must restart IIS for the change to take effect.
