\xff\xf4\xff\xfd\x06 in extranet server's apache log

While troubleshooting a problem in Apache, I thought of trying to send requests to Apache manually through command line :

telnet localhost 80

GET /OA_HTML/jsp/fnd/aoljtest.jsp

Ctrl +C

The GET didn't show up, but the Ctrl+C did:

127.0.0.1 - - [13/Dec/2008:15:38:49 -0500] "\xff\xf4\xff\xfd\x06" 302 - 0

Here's what these x codes mean in Apache:

                       case line

60                                when /\xff\xf4\xff\xfd\x06/

61                                        @sock.write("[*] Caught ^C, closing the socket...\n")

62                                        @sock.close

63                                        return

64                                       

65                                when /\xff\xed\xff\xfd\x06/

66                                        @sock.write("[*] Caught ^Z\n")

67                                        return
