** HTTP GET ** 

GET:  The  method  GET  is  used  to  retrieve/read  a  representation  of  a resource and  should  only  be  used  for  that  purpose When  used  only  for reading is considered safe (no change on the ressource) and even idempotent (one change ). 

But what are the risks ?

  * with an unconstrained use of HTTP/GET 
  * with the intrinsec limitation of HTTP serveur implementation (develop a C# project to illustrate this limitation)
