svn commit: r757427 - /httpd/httpd/trunk/modules/mappers/mod_rewrite.c

Author: jorton
Date: Mon Mar 23 15:59:36 2009
New Revision: 757427

URL: http://svn.apache.org/viewvc?rev=757427&view=rev
Log:
* modules/mappers/mod_rewrite.c (apply_rewrite_rule): When evaluating
  a proxy rule in directory context, do escape the filename by
  default, since mod_proxy will not escape in that case due to the
  (deliberate) fixup hook ordering.

Posted by Jim Jagielski <ji...@jaguNET.com>.
Would it be useful to put some sort of notice of this
in r->notes? Not just here but everyplace we escape.
We get tripped up on this a lot :/

Just a thought (and maybe not a very good one)
