Local fix

Problem summary

• ****************************************************************
  * USERS AFFECTED:  IBM HTTP Server users of the RewriteRule    *
  *                  [B] flag.                                   *
  ****************************************************************
  * PROBLEM DESCRIPTION: URL-sensitive characters are not        *
  *                      being escaped with use of the [B]       *
  *                      flag.                                   *
  ****************************************************************
  * RECOMMENDATION:  Apply this fix if using rewriteRule with    *
  *                  the [B] flag.                               *
  ****************************************************************
  Apache between 2.2.6 and 2.2.11 had a regression where the [B]
  flag stopped escaping most URL-sensitive characters.
  A new BFlagEscapeAllNonAlnum option has been added to restore
  the behavior of escaping all non-alphanumeric characters.
  

Problem conclusion

• To opt-in to the updated 'B' flag handling, the customer will
  need to add the following to each context with 'RewriteEngine
  ON':
   RewriteOptions BFlagEscapeAllNonAlnum
  
  This fix is targeted for IBM HTTP Server fix packs:
  - 7.0.0.39
  - 8.0.0.12
  - 8.5.5.8
