cache.log error messages, please help!

 to squid-list readers:

    I run squid v2.2 - stable 3 on a dell poweredge dual pent2 350 with
a half a gig of ram and over 20 gigs of HD space. It's running a modded
out version of redhat 5.2 with a recent kernel build of 2.2.7. It's acts
as an IP router and gateway for all of my dialup concentrators (ascend
max's) and also for a few on the internal machines on the LAN.

The actual caching mechanism and proxying seems to be working correctly
(except for sore awry errors dealing with ebay's cgi and .dll files) but
I do repetatively get the following errors in my cache.log files:

1999/06/07 06:48:18| clientReadRequest: FD 59 Invalid Request
1999/06/07 08:19:21| clientReadRequest: FD 106 Invalid Request
1999/06/07 08:22:31| clientReadRequest: FD 101 Invalid Request
1999/06/07 09:31:03| clientReadRequest: FD 138 Invalid Request
1999/06/07 11:18:26| parseHttpRequest: Unsupported method 'PROPFIND'
1999/06/06 23:01:00| parseHttpRequest: Unsupported method 'OPTIONS'

I read around on nlanr but couldn't get a definite answer. I was
wondering if somebody could post some information or a place to direct
me. I know log files usually contain 'errors' but i get hundreds upon
hunders of the FD XX Invalid Request and was wondering if it was
anything on MY end or if my end-users are causing the problems.

    thanks, and please, if you respond, post it to the list and cc: me a
copy to my email address.

            -peace, chris
