[mapguide-users] RE: Losing Session ID

Wed Apr 11 13:21:54 EDT 2007

Using the ASP.Net examples from the guide and the ZIP files on OSGEO site
the code starts like this:

<%@ Page Language="C#" %>
<%@ Import Namespace="OSGeo.MapGuide" %>
<!-- #Include File="common.aspx" -->

<%
InitializeWebTier();
MgUserInformation userInfo = new
MgUserInformation("Administrator","adminchangeme");
MgSite site = new MgSite();
site.Open(userInfo);
String sessionId = site.CreateSession();
Session["sessionIdSaved"] = sessionId;
%>

Your Session ID: <%= Session["sessionIdSaved "].ToString();%>

Once you have set the Session variable you can now use the get method
anywhere it is needed. Keep in mind this is ASP.NET code using C# where PHP
would be a bit different but same concept.

You can find the ASP.NET and other examples here:
http://mapguide.osgeo.org/downloads.html

Documentation here:

Regards,
Chris

Hi Chris,

could you give me an example where you would insert these code?

Thanks, Micha
