Subject cvs commit: apache/src mod_dir.c
Date Thu, 28 Nov 1996 17:26:31 GMT
akosut      96/11/28 09:26:30

  Modified:    src       mod_dir.c
  Log:
  Fix directory indexing so that if an index file encounters an error
  that is not 404, it returns that error instead of a directory index.
  This was causing unsafe behavior.
