I need to save a class object in a Session variable. Good? Bad?

[Larry Woods]

Hi,

I am in a situation where I am forced into passing a class object around
between a bunch of pages. The only way that I can figure out how to do it
is storing the object instance in a Session variable. I believe that this
is possible, but my concern is whether it gets destroyed at end of session.

Any comments?

Thanks.

Most of the advice you'll get will probably be a variation on this:

Is there any way you can use a database table to store all the relevant
data from the object, and just store the ID for that row in a session
variable? You could create the object with the appropriate data on each
page, by querying the data, and store the data just before you destroy
the object at the bottom of the page. (I'd use include files for this.)
You could make the ID into a cookie if you wanted the data to persist
past the session.

Yeah, Kris. I knew the answer to "store an object in a Session variable" is
"NO!", but I have a BUNCH of arrays, variables that are being used in the
component. I have decided to get the values thru GET properties, store the
values in Session variables. I'll then recreate the object and reload the
variables via LET properties when I need the object again. Bunch of typing,
but safest.

Thanks,

That is the best way to do it really. Rather than lots of
properties you could try using a serialise technicque
where you get your object to return its data as an XML
string, and give it the ablity to restore itself from this
xml also.
