hi
i have 2 applications where session [ login user] has to be passed from 1st application to the second application.
in my 1st application i have a querystring which holds the redirect url to the next application with the session values[ login user].
the file is redirected to 2 nd appliaction and the session is becoming null[ login user].
can you please guide me along with steps which will be very useful on how to get the session values[ login user] to the 2 nd application. as soon as possible.

0	This is related to the concept of sign-on (SSO).You can do it easily if you are using asp.net 2.0/3.5/4.0 Cookied Cross-Application Behavior You can use diff applications to the cookieless sample to also show cross-application redirects in the cookied case. Again using two sample applications (App1 A and AppB), both applications need to share a common configuration: <forms cookieless="UseCookies" enableCrossAppRedirects="true" path="/cookiedAppA"/> <machineKey decryptionKey="A225194E99BCCB0F6B92BC9D82F12C2907BD07CF069BC8B4" validationKey="6FA5B7DB89076816248243B8FD7336CCA360DAF8" /> To simulate isolation of the forms authentication cookies, each application explicitly sets the path attribute as shown above. Because this sample uses cookies, the path attribute prevents the browser from sending the forms authentication cookie for one application over to the second application. Remember that setting the path attribute only takes effect when using cookied modes (for example, setting the path attribute would have no effect on the previous cookieless example). For now, we will use the same redirection helper as we did earlier, and pages in both applications will issue a Response.Redirect to get to the second application. //First application button click FormsAuthentication.RedirectFromLoginPage("testuser", false); Response.Redirect("/cookielessAppB/default.aspx"); -Hope this works.cheers!

Cookied Cross-Application Behavior
You can use diff applications to the cookieless sample to also show cross-application redirects in
the cookied case. Again using two sample applications (App1 A and AppB), both applications need to share a common
configuration:
<forms cookieless="UseCookies" enableCrossAppRedirects="true"
path="/cookiedAppA"/>
<machineKey
decryptionKey="A225194E99BCCB0F6B92BC9D82F12C2907BD07CF069BC8B4"
validationKey="6FA5B7DB89076816248243B8FD7336CCA360DAF8"
/>
To simulate isolation of the forms authentication cookies, each application explicitly sets the path attribute
as shown above.
Because this sample uses cookies, the path attribute prevents the browser from
sending the forms authentication cookie for one application over to the second application. Remember
that setting the path attribute only takes effect when using cookied modes (for example, setting the path
attribute would have no effect on the previous cookieless example). For now, we will use the same
redirection helper as we did earlier, and pages in both applications will issue a Response.Redirect to
get to the second application.
//First application button click
FormsAuthentication.RedirectFromLoginPage("testuser", false);
Response.Redirect("/cookielessAppB/default.aspx");

0	create temp table in SQL while redirect to another application store the values into temp table and retrieve the session value and assign in the 2nd application session. ex.. DB column=Session["Username"] in 2nd application if(querystring("link") =="fromApp1") { SEssion["Username"]= retrieve from DB. } Make sure you store with some uniqueidentier values thata pass in querystring and retrieve based on that Shubhashree, if this helps please login to Mark As Answer. \| Alert Moderator

create temp table in SQL while redirect to another application store the values into temp table and retrieve the session value and assign in the 2nd application session.

ex..

DB column=Session["Username"]

in 2nd application

if(querystring("link") =="fromApp1")
{
SEssion["Username"]= retrieve from DB.
}

Make sure you store with some uniqueidentier values thata pass in querystring and retrieve based on that
