Problem summary

• ****************************************************************
  * USERS AFFECTED:  Users of IBM HTTP Server (powered by        *
  *                  Apache).                                    *

  * PROBLEM DESCRIPTION: mod_rewrite will generate invalid       *
  *                      URLs for redirects to IPv6 literal      *
  *                      addresses.                              *

  * RECOMMENDATION:                                              *
  ****************************************************************
  mod_rewrite will generate invalid URLs for redirects to IPv6
  literal addresses.
  For example, a RewriteRule such as
  RewriteRule ^/redirect_me /some_url/ [R]
  will generate an invalid URL for following request:
  http://[::1]/redirect_me
  The invalid URL generated from mod_rewrite will look like
  http://::1/some_url/
  

Problem conclusion

• mod_rewrite was updated to generate valid URLs for redirects
  to IPv6 literal addresses.
  
  This fix is targeted for IBM HTTP Server fix packs:
   - 7.0.0.43
   - 8.0.0.14
   - 8.5.5.12
