Actually you are right Michael. and i know it's bad design.
For long-running process , with ajax or no ajax, if the web method
takes longer than script timeout, we are going to have problems.
I can change the timeout period to lets say 5 min. but this is not the
solution, what if the process longer than the script timeout again.
i'm still looking for a best solution.
1- Using Asynchronous delegation
2- Message queue as you offer
3- increasing script timeout period
4- One Way Web Services, if you dont return response to the client.
it's like fire & forget. ( method 1 )
And one interesting solution (actualy not a solution) i found is if you
set the compilation debug mode set to true , request isnt timeout.
But i dont know how much effect performance of the application or
server.
