I am calling https://technet.rapaport.com/HTTP/JSON/Prices/GetPriceSheet.aspx to download prices in JSON format. However, if I am correct, your REST service is returning the incorrect Content-Type in the header. It is coming back with "text/html" as the Content-Type (see below):
Content-Type →text/html; charset=utf-8
Date →Tue, 09 Apr 2013 20:14:45 GMT
Can you please fix this as it should be "application/json"?
