NSURLConnectionDelegate for self signed

web.m

//
// Description
// ----------------
//
//  This is sample for handle self sigined certificate.
//
//  This code have 3 way for building.
//
//   - Default  : Can't connect self signed certificate server.
//   - AUTH     : Can connect self signed certificate server by old style.
//   - AUTH_NEW : Can connect self signed certificate server by new style.
//
// Command usage
// ----------------
//
//  ./urlcon http(s)://xxxxx.com/
//
//
// Compile command
// ----------------
//
// Default : not handle authenticate
//
//   clang -g -Wall -fobjc-arc -o urlcon web.m -framework Foundation
//
//
// AUTH : handle old style
//
//   clang -g -Wall -fobjc-arc -o urlcon web.m -framework Foundation -DAUTH
//
//
// AUTH_NEW : handle new style
//
//   clang -g -Wall -fobjc-arc -o urlcon web.m -framework Foundation -DAUTH_NEW
//
//
// Note
// ------
//
//  Perhaps iOS 5 can't support DSA signature algorism.
//  Mac is running this code.
//
