Using a Customized Global.asax File
Each Logi application includes a file named Global.asax, which is standard in ASP.NET applications. This file is compiled in our Java products and is not accessible for customization. As distributed, it contains only one line of code. However, event handlers can be placed here which react to ASP.NET object events, such as Application_BeginRequest and Session_Start.
Here's a sample:
<%@ Application Codebehind="Global.asax.vb" Inherits="rdWeb.Global" %>
<script language="VB" runat="server">
Sub Session_Start(ByVal sender As Object, ByVal e As EventArgs)
Dim rdServer As New rdServer.rdSession()
Dim myURLQStr As String = "rdProcess.aspx?rdProcess=myProcessDef&rdTaskID=mySessionStart"
' start the new session
' if session already exists, does nothing
' test flag to see if session has already been started
' if not, then do the redirect to the process task
If Session("myStartFlag") = Nothing
' save original query string to session variable for later access
Session("myQueryString") = Request.QueryString.ToString()
' redirect to Process task: mySessionStart
' set session counter
Session("myStartFlag") = 1
In the example VB code above, the user is automatically redirected to a Process task called "mySessionStart" when a new session is started. The URL defined as "myURL" is a relative address, and therefore doesn't need the "http://..." part of the address. So, as another example of how to assign dynamic datasource connection strings, the code above could be adjusted to assign a connection string to a session variable and then call a Logi report.
The two lines of code that reference the rdServer object are required, or your application will not start. Caveat: this example is offered here for consideration by experienced ASP.NET developers but custom code written by developers is outside the scope of our typical support offerings.
