Recently I had a weird problem while using Tomcat - sessions would get lost when using Microsoft's Internet Explorer.
Since Tomcat stores the session id as JSESSIONID cookie, the session would get lost when the cookie is not stored.
Same behavior occurs with other web servers including IIS and Resin.

After further research, it seems that IE does not store cookies at default privacy settings unless a P3P policy is
provided for the site. In order to bypass this problem, a basic P3P policy needs to defined and included in the site.
I used IBM's P3P editor to generate a basic P3P XML policy file and the following snippet of HTML code to enable it.

This is still true as of 2011: [http://blog.toppingdesign.com/2011/11/18/ie-iframe-p3p-cookies-oh-my/]

' The problem with PostgreSQL is lack of documentation for Windows interfaces. Visual Basic uses
' the ADO library to connect to the PostgreSQL ODBC driver, which in turns connects to the server.
'
' This example covers a unique requirement - the network has over 300 individual desktop machines,
' all of which must be able to access the planned PostgreSQL server via Access, VBA or VB6.
' However, they do not want to go and setup a data source name (DSN) on each machine separately
' (installing ODBC is easier via the Windows deployment tools). Unfortunately, the ODBC driver has
' absolutely zero documentation as to how to setup an ADO connection WITHOUT a DSN. After some prolonged
' tries and failures, we both were finally able to come up with a solution which I am posting here for
' others to benefit from.
