Seems to be some automatic advertising / content push thingy, but who
knows what other functions there might be in the client.

The digit string is supposed to be a HTTP/1.1 ETag value, but I have to
agree with you that this server behaves more than odd with the ETag
values which MIGHT indicate the usage of hidden HTTP/1.1 cookies.
However, I haven't actually tested how IIS/5.0 behaves wrt ETag support
so the seen irregularities might simply be bugs/misfeatures in the
server..
