restrict the servers that Haskell's http-client will use; documentation

 Addition to the http-client and http-client-tls Haskell
 libraries, that restricts the HTTP servers that can be used.
 .
 This is useful when a security policy needs to, e.g., prevent connections to
 HTTP servers on localhost or a local network, or only allow connections
 to a specific HTTP server.
 .
 It handles restricting redirects as well as the initial HTTP connection,
 and it also guards against DNS poisoning attacks.
 .
 This package provides the documentation for a library for the Haskell
 programming language.
 See http://www.haskell.org/ for more information on Haskell.
