Delphi Network programming -

-

i have classic client/server (fat client , database) program written in delphi 2006. when conditions met in client, need notify other clients quickly. until has been done using udp broadcasts, no longer viable clients connect outside lan , udp broadcast limited local network.

i'm aware of indy libraries not sure of components use , how structure it. i'm guessing i'll need have server clients connect receive , distribute messages...? samples out there me started?

are there other component sets or technologies should @ instead/as well?

the simple answer standard protocols available in delphi (and other tools) don't allow notification in reverse. looked project wanted use soap. assume client asks server, server responds , that's it.

for me, solution remobjects sdk. allows send notifications clients, , notification can have data (just client server). myself use supertcp connection, works others too. can still offer soap interface clients must use it, have control of both client , server works extremely well.
