Is there navigation rule to know the user came from .xhtml page?

[boy18nj]

<navigation from-action="#{facilityHome.persist}">
<rule if-outcome="persisted

Above navigation rule works, if action is performed on java side.
I am looking for a navigation rule where i can figure out the user came from .xhtml page?

Would you like disable the using of xhtml pages?
If this is your purpose, just add the next lines to web.xml

<security-constraint>
          <display-name>Restrict raw XHTML Documents</display-name>
          <web-resource-collection>
               <web-resource-name>XHTML</web-resource-name>
               <url-pattern>*.xhtml</url-pattern>
          </web-resource-collection>
          <auth-constraint />
     </security-constraint>
