Class HttpUtil

java.lang.Object
  org.brickred.socialauth.util.HttpUtil

public class HttpUtil
extends Object

This class is used to make HTTP requests. We did try NOT writing this class and instead use Apache Commons HTTP Client. However it has been reported by users that Commons HTTP Client does not work on Google AppEngine. Hence we have handcoded this class using HTTPURLConnection and incorporated only as much functionality as is needed for OAuth clients. This class may be completed rewritten in future, or may be removed if a version of Commons HTTP Client compatible with AppEngine is released.
