    We have a working application which uses Server session variables as a
    means to identify the user.

    My boss want to start looking at the IIS logs to understand what our
    users do. On our website we have occasional users and also customers
    for which we have an ID. We would like to be able to link IIS log data
    to internal data via the customer ID, even when we know it is not the
    100% of our users.

    I'm not sure if I should replace the Session("CustomerID") for a
    MySession("CustomerID") that also writes a Cookie which will in turn
    be logged in IIS. Or write the ASP.NET_SessionID along with our
    CustomerID to a table in the database. And if I do should I mess with
    the current page inheritance or just make the call like
    MyLib.MySession(Me, "CustomerID") .

    For security reasons I just don't want to use an ID returned from a

    Has anybody dealt with this? Will sombody come forward and give a
    suggestion? Please?

  2. The first approach with a cookie is the easiest and quickest, I think.

    OK, let's assume I do, Should I code it like MyLib.MySession(Me,
    "CustomerID") and avoid dealing with inheritance. Or should I code it

  4. I think all what you need is to set a cookie

    Response.Cookies["CustomerID"].Value = Session["CustomerID"];

    Note, you will need a reporting tool which could read that values from
    the IIS log.

    It's just easy to miss. I'd like something more foolproof.

  6. What would make it more foolproof?

    When you save a cookie, the cookies will be logged in IIS log among to
    other data, making them available together to be used in your
    reporting. If you gonna save that CustomerID somewhere else, like in a
    database, you will have a problem to link the ID and IIS log.

    OK, I did not make mysefl clear. The line:

    Response.Cookies["CustomerID"].Value = Session["CustomerID"];

    Could be easily missed during programming. We don't have a strong
    testing team here, and we would en un with pages that are not being

  8. Ah, got it! You should set the cookie only once, in your
    authentication form (e.g. login.aspx). The default expiration date of
    a cookie is the current session. It means this cookie will expire when
    the session is ended. Or you can explicitly set the date, for example
    +1 year. It could help to track existed customers who has not

    You can also use global.asax, e.g. Application_BeginRequest() method
    (for all requests) or Application_AuthenticateRequest() (for
    authenticated users only).

    I thought we had multiple points of entry, and that they could
    increase. But it's not the case.

    I think, I complicated myself on this one.

    This is a good suggestion too. I'll keep it in mind.
