What happens when web service receives a request from the client ?

[=?Utf-8?B?S2F1c2hhbCBNZWh0YQ==?=]

Hi,

Could you let me know what exactly happens when web service provider
receives request from the client (from system perspective, like threading and
all) ?

Also, how does the web service store the callback address of the web service
client so that asynchrony can be acheived (from system perspective) ?

Also, can we have message pattern where in client sends the callback address
to the web service provider and then using the callback address, web service
provider communicates with the client as and when required (even without any
further request from the client) ?

The specifics will depend on which version of which platform you're
referring to. ASP.NET ASMX web service running .NET 2.0 on Windows Server
2003 will be a different answer than WCF Web Service running .NET 3.5 on
Windows XP. This will be totally different from Java web services running
in WebSphere on Linux.

As to your questions on callback address, a web service communicates only
with XML. It knows nothing about addresses, unless you are referring to the
IP address and port of the caller.
