I am workinig on a client/server project. Now I have planned to write a
corresponding webclient. In my system, when a client requests, the server
won't reply back immediately (except for ack), instead it will notify the
client sometime back.. and for this the client will run another server,
that will get the server responses.
The problem comes when I tried to think this in terms of webclient. How
is this ("event-notification") possible from client browser. (Oh, no I am
not taking about refreshing the browser window repeatedly).
I remember the interface of Yahoo! briefcase fileuploads. It displayed a
animated progress bar. No contest was loading at that time (i.e. the
browser progress bar was idle). But after sometime (after the file got
uploaded), a new page got loaded (finished uploading).
The restriction is, I shouldn't open/connect to any port other than 80 on
