What is the easiest framework to use so that my application can make a
synchronous call to another server on the web.  As an example, this server
is waiting to receive an xml request which looks like the following:

<methodCall>
- <applewebdata://B2A0B5EA-4815-4FD0-BBDE-DA3300549DA0#><methodName>
sample.sumAndDifference
</methodName>
- <applewebdata://B2A0B5EA-4815-4FD0-BBDE-DA3300549DA0#><params>
- <applewebdata://B2A0B5EA-4815-4FD0-BBDE-DA3300549DA0#><param>
- <applewebdata://B2A0B5EA-4815-4FD0-BBDE-DA3300549DA0#><value>
- <applewebdata://B2A0B5EA-4815-4FD0-BBDE-DA3300549DA0#><int>
3
</int>

</value>

</param>
- <applewebdata://B2A0B5EA-4815-4FD0-BBDE-DA3300549DA0#><param>
- <applewebdata://B2A0B5EA-4815-4FD0-BBDE-DA3300549DA0#><value>
- <applewebdata://B2A0B5EA-4815-4FD0-BBDE-DA3300549DA0#><int>
11
</int>

</value>

</param>

</params>

</methodCall>


I know how to make calls, for example, to the amazon site to do book
lookups, etc using NSURL, NSURLRequest and NSURLResponse.

Thanks for any quick guidance someone can point me to.
