Got Objects in Sessions working, but Handles are not maintained.

[Jon Grieve]

Hi,

I've been playing for a few days now with putting Objects in sessions
and maintaining that object during a session. This seems to be working
just fine, and I can see and use most of the functionality without a hitch.

In my particular case, I have a Class that performs various TCP/IP
functions. Basically, it connects to a device using telnet and
interacts with that device. I open the connection and login as part of
my class, and I want to keep that connection established so that the
various pages can issue a command without having to re-connect and
re-login each time.

So, for example, I do a socket_connect( ) early on and want to maintain
that connection while the class is passed from page to page. However,
after the first use of the socket and subsequent redirect to another
page, I find I have a valid class with all its properties intact, but
the socket handle (a property itself) seems to have become invalid.

Make any sense? Anyone got any clues?

Thanks,
Jon

I guess you can't do that.
A socket is a /resource/ and resources cannot be serialized, therefore
they can't be saved in session variables (unless there's another way to
save them other than serializing ... ?)

It seems you're stuck with opening and closing the connection for every
access. Somebody please tell us I'm wrong :)
