4    * This class is used to keep track of a thread local instance
5    * for rewriting URLs - ultimately for deciding if a link should
6    * be decorated 'secure' (as in config value secureUrl) or plain.
7    *
8    * The initialization (and clean up) is meant to be done in a
9    * servlet filter, so that the thread local rewriter is available
10    * to each request. This is done because a blog itself serves its
11    * Url to anybody and doesn't know how to determine if it should be
12    * talked to 'secure' or not.
13    *
14    * In the current scenario, secureUrl may be used for logging in
15    * and performing administrative work. Be aware though that mixing
16    * http and https access to an application may itself impose severe
17    * risk while the user feels comfortably safe. Best and most secure
18    * mode for operation would be to go https exclusively. If you
19    * can't, the current solution (this class is participating in)
20    * will help you the best it can.
