Subject cvs commit: apache/src alloc.h alloc.c http_protocol.c
Date Tue, 27 May 1997 04:14:23 GMT

  Modified:    src       alloc.h alloc.c http_protocol.c
  Log:
  Two problems were introduced by the two "error responses have wrong headers"
  patches committed a couple weeks ago.  The first is that a NULL table
  causes mod_log_config to SIGSEGV on a call to table_get; the second is
  that Location needs to be added to the output header table for redirects.
