Subject cvs commit: httpd-2.0/server protocol.c
Date Mon, 06 May 2002 09:11:51 GMT
jwoolley    02/05/06 02:11:51

  Modified:    server   protocol.c
  Log:
  cleanup old-school backward uses of APR_BRIGADE_CONCAT to use
  APR_BRIGADE_PREPEND instead, plus optimize away a bunch of repetitive
  brigade destructions/creations by hanging onto ctx->saved even after
  we empty it out.
