use calloc instead of malloc and we won't have to memset() the struct

  bool badcookie = FALSE; /* cookies are good by default. mmmmm yummy */

  /* First, alloc and init a new struct for it */

  co = (struct Cookie *)malloc(sizeof(struct Cookie));

  co = (struct Cookie *)calloc(sizeof(struct Cookie), 1);

  if(!co)

    return NULL; /* bail out if we're this low on memory */

  /* clear the whole struct first */

  memset(co, 0, sizeof(struct Cookie));

  if(httpheader) {

    /* This line was read off a HTTP-header */

    char *sep;
