<DIV><FONT face=Arial>Dear Bernard,</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>We had the same problem with one of our clients who didn't
want the OpenCms Workplace to be accessible to outside users.</FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>We used Java servlet filtering technology (supported by
Tomcat) to filter all requests, and block all outside requests to the Opencms
Workplace. </FONT></DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Maybe someone else has a simpler, smarter solution, but at
least this works fine.</FONT> </DIV>
<DIV><FONT face=Arial></FONT> </DIV>
<DIV><FONT face=Arial>Best regards,</FONT></DIV>
