<p>This property defines the case sensitive URL-pattern matching
behavior for security constraints, servlets, filters, virtual-hosts,
etc. in the WebApp container and external security policies.
When the value is set to "os", the pattern matching will be case-
sensitive on all platforms except the Windows file system.
Note that on non-Windows file systems, WebLogic doesn't enforce
case sensitivity and relies on the file system for optimization.
Therefore, if you have a Windows Samba mount from UNIX or Mac OS
that has been installed in case-insensitive mode, there is a chance
of security risk. In that case, please specify
case-insensitive lookups by setting this attribute to
<code>true</code>.
Note that this property is used to preserve backward compatibility on
Windows file systems. In prior releases, WebLogic was case-
insensitive on Windows. Starting with 9.0 release the URL-pattern
matching will be strictly enforced.
During the upgrade of older domains the value of this parameter
is explicitly set to "os" by the upgrade plug-in, in order to
preserve backward compatibility. </p>
