Sp Not Returning Output

i have the following stored procedure which does a hit to a server and returns the response

it is hitting the server but the problem is the response is null


any ideas what i'm doing wrong

/****** Object: Stored Procedure dbo.http_geturl Script Date: 2/12/2007 2:00:40 PM ******/

if @hr < 0
