APM Session Visibility across VIPs

    The browser must simply include the cookie in the request to be associated with the session. RFC 6265 defines exactly how this works, if you aren't familiar with it. The wikipedia article on HTTP cookies is also very good.

     

    Customers usually choose one of the following options to share the cookie across multiple vips/hostnames:

     

    1. Set the cookie domain to be wide like ".company.com" so that the cookie will be transmitted to *.company.com.

       

    2. Use APM's multi-domain mode so that when APM gets a request without a cookie, it will "check with" the domain set as the primary-authentication URI to see if it's been set. This happens by using some 302 redirects between the hostanmes/vips.

       

    For either of these options, make sure the session scope is set appropriately.
