Question

I used a sql server session mode between two web applications.
The session id is created in the ASPState database. I need to share the session id from first application to second without using querystring and cookies. I followed the steps from this link. Below is the code.
In both apps (web.config)

<add name="DBConnection" connectionString="Data Source=localhost;DataBase=ASPState;Integrated Security=True;uid=sa;pwd=password-1" providerName="System.Data.SqlClient"/>

<sessionState mode="SQLServer" sqlConnectionString="DBConnection" allowCustomSqlDatabase="true" regenerateExpiredSessionId="false" cookieless="false" timeout="1" ></sessionState>         

<machineKey validationKey="566A547C407CB0C47ABAEC581B8B90C45E15039806352E4611B35E0FB70C1C096350A4BBAE816191331DCA55874D3F96B41FFDED4C6A913591684A90825F53A0" decryptionKey="B299127DFC22648C2EF92D7EDF2E4960277F562C60F3BDE4A4C3BFDFEA602FDF" validation="SHA1" decryption="AES" />
<modules runAllManagedModulesForAllRequests="true">    
<add name="BasicAuthenticationModule" type="UserAuthenticator" />
</modules>

In first app Home.aspx.cs

protected void imgBTN_Click(object sender, EventArgs e)
{
   string sessionKey = HttpContext.Current.Session.SessionID;
  //How to transfer the same session id to the second application
   Response.Redirect("http://localhost:43392/PartnerHome.aspx"");
}

I got the session key from ASPState database. But how to pass from the same session id to the second application ?

Answer 1

You can use SessionManager to set the ID to whatever you want in the target site. You just need to pass it via querystring GET or form POST from one to the other:

Source

Response.Redirect("http://localhost:43392/PartnerHome.aspx?SessID="
    + Session.SessionID);

Target

string sessionId = Request.QueryString["SessId"];
bool redirected = false;
bool isAdded = false;
new System.Web.SessionState.SessionIDManager().SaveSessionID(
    HttpContext.Current, sessionId, out redirected, out isAdded);

See SessionIDManager on MSDN
