/**
 * Purpose of this method is to process redirect case. A lot of sites are NOT compatible to HTTP RFCs. It means
 * that they may specify redirect in wrong way. For correct way refer to http://www.ietf.org/rfc/rfc2616.txt 14.30.
 *
 * Let's say we received redirect directive from external server after requested http://www.w3.org/Whois page.
 * Below are the variants we may've received and the ways we will treat them:
 * <code>//from  ww w .  j a  v a  2  s  .c  om
 * <ol>
 * <li> "http://www.w3.org/pub/WWW/People.html" - correct redirect, no questions
 * <li> "/pub/WWW/People.html" - resolve to http://www.w3.org/pub/WWW/People.html
 * <li> "pub/WWW/People.html" - resolve to http://www.w3.org/pub/WWW/People.html
 * <li> "" - resolve to http://www.w3.org/
 * </ol>
 * </code>
 *
 * Please add the cases if you found anything else we may suffer from on redirect matter.
 *
 * One more note. Why this couldn't be done in a regular method {@link #createUriWithSchemaAndPath(Object)} ,
 * why we need separate one. Regular one deals with user input with no URI context built in. Redirect case
 * ALWAYS has context - the page it was redirected from. User meaning of something.page is (try it in browser!)
 * http://something.page. Redirect meaning of the same is most likely http://theHostRedirectCameFrom/something.page.
 *
 * @param redirectTo string saying where we should be redirected
 * @param hostRedirectedFrom host we received redirect from
 * @return resolved URI
