Problem summary

****************************************************************
* USERS AFFECTED:  Users of IBM HTTP Server (powered by        *
*                  Apache) on z/OS using mod_rewrite and       *
*                  mod_authnz_saf.                             *
****************************************************************
* PROBLEM DESCRIPTION: A 404 error is returned for some file   *
*                      urls processed by RewriteRule when      *
*                      mod_authnz_saf is loaded.               *
****************************************************************
* RECOMMENDATION:  Apply this fix if using RewriteRule with    *
*                  mod_authnz_saf loaded.                      *
****************************************************************
mod_rewrite is running earlier than intended and seeing
un-decoded URLs when mod_authnz_saf is loaded.
This leads to files not being served and a 404 being returned.

Problem conclusion

mod_rewrite no longer runs early, so all characters will be
decoded by the time RewriteRule processes a url.

This fix is targeted for IBM HTTP Server updates:
 - 7.0.0.41
 - 8.0.0.13
 - 8.5.5.10
 - 9.0.0.0-PI54808

Temporary fix
