<P>
A <code>PathMatchingFilter</code> that will disable creating new Sessions during the request. This is a useful
filter to place in the front of any filter chains that may result in REST, SOAP or other service invocations that
are not intended to participate in a session.
<p/>
This filter enables the following behavior:
<ol>
<li>If a <code>Subject</code> does not yet have a Session by the time this filter is called, this filter effectively
disables all calls to <code>subject</code>.<A HREF="../../../../../../org/apache/shiro/subject/Subject.html#getSession()"><CODE>getSession()</CODE></A> and
<code>subject</code>.<A HREF="../../../../../../org/apache/shiro/subject/Subject.html#getSession(boolean)"><CODE>getSession(true)</CODE></A>. If either are called
during the request, an exception will be thrown.</li>
<li>
However, if the <code>Subject</code> already has an associated session before this filter is invoked, either because it
was created in another part of the application, or a filter higher in the chain created one, this filter has no
effect.
</li>
</ol>
Finally, calls to <code>subject.getSession(false)</code> (i.e. a <code>false</code> boolean value) will be unaffected
and may be called without repercussion in all cases.
