Hi Everybody,
I administrator a intranet web site. I found that there
are IE 6 (on Windows 98 or 2000) that sending out extra
requests for default home page. These extra requests are
transparent to the users, but seen on the IIS log. e.g.
14:41:31 xxx.20.135.181 - GET /queries/loginDlog.cfm
14:41:31 xxx.20.135.181 - GET /index.cfm
14:41:31 xxx.20.135.181 - GET /index.cfm
14:41:36 xxx.20.135.181 - POST /queries/loginDlog.cfm
14:41:36 xxx.20.135.181 - GET /index.cfm
14:41:46 xxx.20.135.181 -
POST /queries/Pathology/PATHPatientShow.CFM
14:41:46 xxx.20.135.181 - GET /index.cfm
14:41:55 xxx.20.135.181 -
GET /queries/Pathology/PATHPatientRslts.cfm
14:41:55 xxx.20.135.181 - GET /index.cfm
14:42:21 xxx.20.135.181 -
GET /queries/Pathology/PATHPatientRslts.cfm
14:42:21 xxx.20.135.181 - GET /index.cfm

In this example, the default home page is /index.cfm. But
it can be /default.htm.

Are these PCs got infected with some sort of virus?
Anybody see this strange behavior before?

Thanks

We are on IIS version 4 (service pack 6). In my last mail, I didn't show
the complete IIS log for ease of understanding. Our log includes
Time,IP,User Name,Method,URI Stem,URI Query,Http Status,Win32
Status,Bytes Sent,Bytes Received,Tme Taken, Protocol Version,User Agent,
Cookies, Referrer. Below is the 'complete' log without Cookies (which is
too long to display). Anyway, those additional requests all have Status
200, 6200 bytes sent, 422 bytes received and no Http Referer (denoted by
a dash "-").

I don't quite get you. what's the version of IIS ?
you need to log more field/info in the log file, e.g. status, username

what's the default pagename ??

Mm.. weird. so it's making 2 default page request
with referrer '-'.

For double request, is there any self direction in the
index.cfm itself ?? is all visit from all machines exhibits
this behavior ?

As for the referrer field showing '-', I have no ideas :(
