Web Services Async Call With Ajax

Hi All,

Iam developing an app that, based on a common search criteria, do requests to 3 different web services , parse the responses and render the info back into a view; What Im trying to do is: via Ajax (async), send the requests to the WS and render the response of each Ws in a different div ; Here Im stuck, because the WSs doesnt allow async calls , so i have to handle the async calls in some other way…

Can anyone point me which could be the best approach to do this???

Sorry for the bad English
