@Thomas

Thanks for the info. Having couple of issues:

   1. I'm posting request to another server and having issue because of 
   cross-origin. I verified this by forcing browser to allow to allow 
   connection
   2. This is async call. So, if I try to send request and based on that 
   return text-result; it won't work. I have a method that includes (has 
   return value). The caller immediately receives the return before the 
   request has completed its call. I think I need to think of another 
   approach. Any suggestions?
   

Thanks
