using the wrong header for REQUEST ?

[ronmmn]

I suspect you are using the wrong header in the REQUEST :
Access-Control-Allow-Origin
From what I know - this header is part of the RESPONSE from the server handling CORS for your request. You should be using Allow-Control-Request-Origin instread.
Am i right ? I really looking forward working with your framework, ui-http.ts

Where can i see some usage example for UIHttpService?
My goal is to perform WebAPI calls.
