Shahzad:
(Again assuming I understand your current question,) I don't really see why
dynamically generated values (presented in <tr><td>'s or anywhere else in your jsp)
should not be saved in session variables (or even static variables if they will be
common to all users). Here's what you can do in psuedo-code:
The first time that you generate your jsp, save all data that you pick up from the
db in session/static vars. Then, as before, write code in your jsp as follows:
if (db-session-var-value is null) {
go to db and pick up values to present;
save the values in session vars. for the next time this jsp is displayed;
}
else present the value in the session variable (within <tr><td>'s or whatever..)
The only time this will not be ok is if the submission of the form by the client
will cause different values to be saved in the database (due to updates/writes to
the database, etc.). In which case, I would think you would *want* to go to the
database again.
I believe though that this above approach goes against the MVC idea of using JSPs
only for presentation purposes. You may want to use a (controller) servlet to save
the database values in an appropriate bean, save that bean in a session variable and
then use that bean to display the jsp.
Regards,
Geeta
P.S. Unless I grossly misunderstand your question, I don't think using HTTPS makes
much difference to your problem.
