Sometimes it is important that neither the web client (or proxy server) nor Domino caches the form that is being processed. You can the use the following in the "HTML Head Content":
"<META HTTP-EQUIV=\"cache-control\" CONTENT=\"no-cache\">" + @NewLine +
"<META HTTP-EQUIV=\"Pragma\" CONTENT=\"no-cache\">" + @NewLine +
"<META HTTP-EQUIV=\"Expires\" CONTENT=\"0\">" + @NewLine;
FIELD $CacheOptions:="0";
FIELD $CacheValid:="0";
