I'm not sure if this is at all relevant, but a user of a site
that I run has recently been having problems logging in using
IE5 on Windows 98. When
I investigated I found that when she entered her user name
and password she was authenticated sucessfully and a session id
was generated. This session id was sent as a cookie, but for
some reason was not overwriting an old cookie (which contained
a session id no longer in the database) with the new value.
The only solution that I found was to delete the cookie. I assume
that it had been corrupted in some way. Does anyone know if
this is a common problem, and if there is anything one can
do to avoid it when setting cookies?
