I'm now confused by what the pointer says:

'Therefore you can compare the size of the file (1456 in the above
example) to the size of the corresponding file in your default server. If
they are the same, then the proxy attempt failed, since a document from
your server was delivered, not a document from www.yahoo.com.'

In our situation, proxy is not on.  There are no corresponding files
(4021489C329206511 and 3467595C1541548350) on our web server for the
following requests.  So the following attempts actually succeeded??

==
222.185.24.17 - - [30/Aug/2006:08:37:57 -0500] "GET

222.185.24.17 - - [30/Aug/2006:08:38:03 -0500] "GET

"http://www.interstfree.com"; "Mozilla/4.5 [en] (Win98; I)"

The part after the ? is the query string, not the filename.  Do you
have a directory "ppv" on your server?  If so, this might be normal.
If not, you are either proxying requests or you are returning 200
(success) status codes for requests to non-existant files.  Either
way, you have a problem.
