I've built an ASP.NET web service with .NET 2.0 (an asmx file). I invoke a web service method using Ajax. The method takes a substantial amount of time to execute (5 minutes to 1 hour). I believe it's not a good idea to "hang" the web request for so long.
I'm wondering if the web service method could spawn an additional process which in turn would execute the lengthy operation and notify the web service once the operation is completed.
Are there any good practices regarding this kind of functionality?
