double cookies - same name - .Net bug?

I'm using the following code in my .Net application (.Net v1.1, Windows
2000) to write Session Cookies.
HttpContext.Current.Response.Cookies("cookieSessio n")("SessionID") =
strSessionID

HttpContext.Current.Response.Cookies("cookieSessio n")("Site_ID") =
strSite_ID

HttpContext.Current.Response.Cookies("cookieSessio n")("LanguageCode_ID")
= strLanguageCode_ID

HttpContext.Current.Response.Cookies("cookieSessio n")("ShipZip") =
strShipZip

HttpContext.Current.Response.Cookies("cookieSessio n")("blnLoadDynSide")
= blnLoadDynSide

HttpContext.Current.Response.Cookies("cookieSessio n")("blnProdView") =
blnProdView

HttpContext.Current.Response.Cookies("cookieSessio n")("blnHasCart") =
blnHasCart

HttpContext.Current.Response.Cookies("cookieSessio n")("CatalogCode_ID")
= strCatalogCode_ID

HttpContext.Current.Response.Cookies("cookieSessio n")("SegmentTypeCode_ID")
= strSegmentTypeCode_ID

HttpContext.Current.Response.Cookies("cookieSessio n").Expires =
DateTime.Now.AddDays(10)

Arbitrarily, in Internet Explorer, the cookie is written twice. This
causes major issues w/ my Ecommerce application.

Here's what the IIS log files look like. Notice the cookie with the
same name in there twice.

On your logs looks like there are 2 different IPs:
207.200.116.5
207.200.116.6

Could be one request going to the first IP the second going to the second IP
that's why 2 cookies are being sent with 2 diferent domain?

Just an idea, give me the set up of your IIS. THanks

Domain name is pointed to 216.52.152.116. ISP has a redirect to
192.168.71.201.

The visitor to this site was an AOL person (The
207.200.116.5,207.200.116.6, and the logged IP of 172.191.129.192 are
all pointed to AOL.
), and AOL has multiple proxies. So, my webserver receives requests
from multiple sources. Hmmm... Shouldn't be this way.

Cookies are supposed to be domain name specific, I thought and
shouldn't write a cookie for each IP it comes in on.

I went back to this person's initial visit and they doubled up right
away, so now I'm even more perplexed. Here's their initial IIS record
from 5 days earlier (notice that it's doubled up too).

I am going to disable my Webtrends ISAPI cookie. This may be one of
the root causes as well. Thanks for the help.

This is so weird, cookies should get attached to @domain.com not the IP.
However in your log shows 2 different IPs, Need to check my logs to get an
idea. I'll check back with you soon.

Same scenario as above, writing the blnLoadDynSide in cookie array to
"1". Causes double up. Here's the code again:

HttpContext.Current.Response.C*ookies("cookieSessi on")("blnLo*adDynSide")

= blnLoadDynSide
HttpContext.Current.Response.C*ookies("cookieSessi on").Expire*s =
DateTime.Now.AddDays(10)

Arbitrarily, in Internet Explorer, the cookie is written twice. This
