The netblock is owned by AOL (195.73.x.x/16).  I received about 20-30
requests (albeit valid requests) from what looked like 20 sequential hosts
from within that block.  Further inspection of the logs though showed that
it was from really 1 session (validated thru aspsession identifier).

So my question is, does anyone know whether or not that this is some sort of
valid AOL proxy behavior where a request for a single page can go thru
multiple proxies?  Spawning multiple proxies to request information that
generally only 1 proxy would get.  (ie, a request for a web page resulted in
3 different hosts getting different parts of the page, all off of the same
aspsession id)


Completely normal. From one of the sites I administer (in standard apache
combined format) :

cache-rc02.proxy.aol.com - - [17/Aug/2002:21:03:27 -0700] "GET / HTTP/1.0"
cache-rc01.proxy.aol.com - - [17/Aug/2002:21:03:34 -0700] "GET /file1.jpg
HTTP/1.0"
cache-rg04.proxy.aol.com - - [17/Aug/2002:21:03:34 -0700] "GET /file2.jpg
HTTP/1.0"
cache-rg03.proxy.aol.com - - [17/Aug/2002:21:03:34 -0700] "GET /file3.jpg
HTTP/1.0"
cache-rm04.proxy.aol.com - - [17/Aug/2002:21:03:35 -0700] "GET /file4.jpg
HTTP/1.0"
cache-rm05.proxy.aol.com - - [17/Aug/2002:21:03:36 -0700] "GET /menu2.swf
HTTP/1.0"
cache-rc08.proxy.aol.com - - [17/Aug/2002:21:03:46 -0700] "GET /file6.jpg
HTTP/1.0"

I've trimmed the referrer and useragent fields, but they seem to be valid
as well.
