RE: FLASH: Can you Push to Flash?

[GDavies]

The security model in most browsers does not allow push.  You could

implement push using a java applet and RMI calling a javascript method,

calling flash... but that would be complex and a lot of work.


I would suggest a simple poling mechanism that just polls for events.  (Java

messaging service is a robust solution to push, but expensive in terms of

development and time)


I'm writing an adhoc messaging system right now with my full time job, which

performs a simple poll to find out if there is data, if there is data, I

then submit a simple http request that calls some xml and formats a div tag

containing the messages.  One of the main reasons for not having push to a

client is the size of the client, it ends up being pretty fat, also session

recovery becomes an issue (if a registered client, looses its connection).


I can probably guide you on push pull technologies, as this is my area of

expertise, but maybe off the forum.  I would not recommend trying to use

FLASH for push, but pull would work fine provided your web server could

handle the frequency of polling.
