Domain=kCFErrorDomainCFNetwork Code=303 What does this error code means?

Getting the below error frequently from server.

Error Domain=kCFErrorDomainCFNetwork Code=303 "The operation couldn’t be completed. (kCFErrorDomainCFNetwork error 303.)" UserInfo=0x18a41d20 {NSErrorFailingURLKey=http://ift.tt/1GDcEMW, NSErrorFailingURLStringKey=http://ift.tt/1GDcEMW}

Can any one tell me what is the cause for the issues?
