Since I almost always have some business logic to perform on the server for any data service call, if only to log it, I just make all calls through an asp.net back-end (I use vb.net also) It is not a true "proxy", I don't attempt to redirect urls, but rather use HTTPService to post name=value pairs from Flex to the server. On of the pairs is "action=whatever" which tells the back end how to handle the request, through a Select Case.
I then make my WebService or XMLHTTP call or do my business logic, then wrap the result in an xml root node (with status/error info) and return it to the Flex client. Visual Studio's Web Service proxy generation and debugging make consuming webservices very easy, and I don't ever have any crossdomain issues.

I shouldn't have been so flippant in the earlier post. Obviously what I need is more concrete exampleas of how to do this. My language of choice is ASP.NET, preferably VB. Are there any examples of how to setup a proxy server? If the proxy server approach is so easy to accomplish why doesn't yahoo allow full access via crossdomain.xml?
