How To Use A Dialog Retry Timer For Doing A Web Service Call

Hi Remus,

I just started looking into SB about a week ago, so my question is likely to be pretty lame. However, that's not going to stop me from asking it :-)

We're trying to do something similar to what you're describing here. How do you "reset" a dialog timer? Why would you need to deal with resetting timers (or with timers at all for that matter) in the event of a success? Couldn't you rewrite the logic to be as follows?


begin transaction
receive message
if message is web request
save state of request (http address, caller etc)
else if message is retry timer message
load state of request
endif
commit
do the web request (no transaction open)
if success
begin transaction
send back response
end conversation
commit
else
set a retry timer on the dialog (say 1 minute) using BEGIN DIALOG TIMER
endif

Also, when you set the retry timer you have to associate it with the saved request state, right? Otherwise, how will the service know which request to load on receipt of the timer message?

TIA.
