Subject cvs commit: httpd-2.0/modules/http http_protocol.c
Date Sun, 04 Aug 2002 18:24:11 GMT

  Modified:    modules/http http_protocol.c
  Log:
    Just an observation, we potentially read/retain far too much of the body,
    and this can be optimized.  Not a problem for sendfile based byterange
    requests, but potentially lethal to serve byterange requests of any
    parsed or cgi generated responses.
