I am serving permanent cookies which contain a GUID to uniquely
identify users for subsequent reporting purposes.
Recently I have discovered that on a given machine, while there only
ever seems to be one Cookie referenced in ?Temporary Internet Files'
for my domain (as you would expect), there are sometimes multiple
cookies in the ?Cookies' directory, differentiated from each other by
an integer in square brackets incorporated into the cookie name.
An example I found is as follows:
Cookie:user@mydomain.net/
was in ?Temporary Internet Files', while:
user@mydomain[1].txt
user@mydomain[2].txt
user@mydomain[5].txt
could be found in ?Cookies'
In the above example, user@mydomain [5].txt referenced the actual
cookie in ?Temporary Internet Files' (I know this as they both
contained the same UserID. user@mydomain[2].txt had a different UserID
in it and was 2 weeks older than user@ mydomain[5].txt, and
user@mydomain[1].txt contained nothing (no UserID), and was a couple
of months old.
I have found similar examples on other (though not all) machines.
Also, try as I might, I cant replicate this.
Does anyone know how these apparently orphaned cookies could be ending
up in the ?Cookies' directory?
Any thoughts/ contributions would be gratefully received.
Many thanks,
Jerry
