Flex Flash sending a HTTP request with a dynamically creating url

Hi I've been connecting to my Server side code using HTTP Services.

However I'm stuck on something that I think must be very simple but I'm just not seeing it.

I create a session and the server response is as follows redirecting to

http://localhost:3000/users/126.xml which is exactly what I want.

However on the Flex side I don't know how to read this data into the application.

All previous requests have read the entire database into the applcation for example

returns all users. But I just want user number 126 in this example.

The way I've been defining my http:services is as follows

but I need some way开发者_高级运维 to write

But I can't figure out how to do that. Any ideas?

Thanks in advance.

Change the result format to e4x.
