Clearing your Web browser cache when upgrading
To avoid problems when upgrading software revision levels, Nortel recommends
that you clear your browser cache and exit the browser and all associated windows
(such as mail and news readers). See the following section for browser cache
clearing instructions.
Clearing cache
A browser caches windows to improve performance when the same window is
requested again. The VPN Router's HTTP server allows browsers to cache Java
class files and all image files, but does not allow browsers to cache body windows
that contain the dynamically generated information. Both Internet Explorer and
Netscape allow you to clear the browser cache which causes all windows to be
rerequested the next time they are required. To manually clear the browser cache
in Internet Explorer V4.x, select View > Internet Options, and click Delete Files.
To manually clear the browser cache in Netscape V4.x, select Edit > Preferences
> Advanced > Cache and click Clear disk and memory cache.

Web browser error messages

No data in post message
Cause: This message often appears on the main body window if you use the
browser's back arrow to revisit a previously displayed window. The browser
displays this message when it knows you are revisiting a dynamically generated
window.
Action: To see the window, use the left navigational area to select it.
Internal error message
Cause: The HTTP server was unable to allocate memory. This indicates that the
VPN Router is very low on memory.
Action: Terminate any unnecessary tasks to free up memory. It may be necessary
to reboot the VPN Router. If this condition recurs, there can be a serious problem.
