The “cache” in question isn’t a real cache, so it won’t get invalidated. It will persist for years, so once the workaround is done, your server should be safe. But new installs and unattended servers will need a more automated solution. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Cheers,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>David Cook<o:p></o:p></p><p class=MsoNormal>Systems Librarian<o:p></o:p></p><p class=MsoNormal>Prosentient Systems<o:p></o:p></p><p class=MsoNormal>72/330 Wattle St<o:p></o:p></p><p class=MsoNormal>Ultimo, NSW 2007<o:p></o:p></p><p class=MsoNormal>Australia<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Office: 02 9212 0899<o:p></o:p></p><p class=MsoNormal>Online: 02 8005 0595<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
