Maintain Session State across different Applications

Question

Friday, April 17, 2009 3:28 AM

Dear All,

I want to know whether we can share login information stored in  session variables between 2 different web applications that are present on the same web server.  Basically what I want to do is that user logs in application A and then  I save his login name and password in session variables lets say

Session["username]="sam"
Session["password"]="password"

 Now i want to pass these session variables to a different web application B. and on Page load of web application B I want to retrieve these Session variables. Ideally I want to solve this by using SQL Server 2005 database if possible.  A simple working example would be greatly appreciated.

 cheers,
Sam Solomon

Dear Sir,

 

Thanks for your reply. But I am looking for a SQL Server 2005 solution. I am interested to know how we can handle it using a database.

Well you just need to have both apps pointing at a database using the same connection string, then both apps will be able to see the same data.

There is another option if you just want to share login authentication tickets between apps - you can use something called SSO (Single Sign-On) which is possible by following a tutorial like this:

 I dont think you can share this information between apps directly.

You can store the information in a database yourself and then pass an auth ticket id that references it so that you can pull the information out the database in a different app.

You can't share session objects between applications.

If you use forms authentication cookies, then you can use this in multiple sites so long as each web site had the same machine key and you used a common cookie domain.

 Storing user credentials in the session is a bad practice - if the session gets hijecked the hacker has credentials on the application.

It is not possible to share session data between websites.  What you can do is either work from the same database, then each website will have access to the same data.  Alternatively you could pass the data between websites using the Request.QueryString class.
