I see these HTTP request and I'm looking for more information :

x.x.x.3 - - [08/Nov/2006:05:06:21 -0500] "\x80|\x01\x03\x01" 200 8 "-" "-"

Would it be someone attempting to send https request on my port 80 ?


When I see things like that in my logs it's generally a buffer
overflow attack, or something like that, but the entry will be
a great deal longer.  What's really interesting to me about
your log excerpt is that your webserver successfully filled
the request, whatever it was -- that's what the " 200 " code
means.
