strange http log entry

[James Sinnamon <jps@westnet.com.au>]

Dear firewallers,

I found a two unusual "SEARCH" records on my apache httpd 
access.log.

They start as follows:

144.132.111.231 - - [10/Jul/2004:11:38:24 +1000] "SEARCH
/\x90\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\

\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\

\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\\
x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\
\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\
\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\
\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\
\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\x02\xb1\\
..

Each record is roughly 8180 characteres in length.

Does anyone know what might be going on? Is it perfctly innocent
... or is someone up to no good?  Can anyone suggest another
mailing list on which to pursue this if this is not the right place 
to ask?

The two query records in full are at:

TIA
