Subject cvs commit: httpd-2.0/modules/generators mod_autoindex.c
Date Sat, 20 Oct 2001 18:54:55 GMT

  Modified:    modules/generators mod_autoindex.c
  Log:
    Restrict by content type and encoding before we go and try to drag in some
    text to merge as headers and footers to autoindex pages.  This will escape
    index.gif from a bold attempt to use IndexHeader index ;)
  
    Also pass in the args to the subrequest, for anyone trying to decode what
    the user is looking at.  A great example of this coming up.
