Hi MArk,
Basically you want to send a message from the client to the server
when
there is a problem on the client.
Which version of ULC are you using?
6.1 We are caching data on the client to reduce traffic. At the
moment, the server sends data once and
then assumes it is cached.
We need the client call to flag there was a problem (ie not enough
disk space to cache) so please resend.
I'll try your suggestion.
MArk
In ULC 6.1, you can call a method on the server side proxy from the
client
side proxy using invokeULC() method.
So your client side code will look like:
if (error)
invokeULC(...);
}
Then on the serverside class you can implement a Dispatcher class
which will
delegate the method call to a method in the server side class. In that
method you can send back the data by invoking a method on the
client using
invokeUI(...).
Please read sections 3.4.1 & 3.4.2 of ULC Extension Guide.
I hope this helps.
Thanks and regards,
Janak

Subject: [ULC-developer] Query on how to implement caching
I have a Canoo client class which is being streamed data from a
server.
Some of this data is resent so I have implemented the canoo code so
that when
the data for page 1 is sent, the ULCViewer class logs this and if
Page 1 is resent it sends
a null object rather than resending the 160 k.
On the clientside, if a null object is received then UI Client knows
we have stored the data on disk
and retrieves it.
This works brilliantly until UI client cannot cache the data for some
reason (ie disk problem).
So how can UI VIewer send a message back to ULCVIewer asking for the
data to be resent?
