Solution 1

Session What you CAN do is post the data to your second site and put it in session variable in the second application.

Or you can use domain cookie if you're asking only and specifically about subdomain sites. Something like this
Response.Cookies("CookieName").Domain = ".example.com"

Remember that cookies have size limits though.

If this helps please take time to accept the solution. Thank you.

Solution 2

You can do it in two alternate ways

First: Store session value in cookie and retrieve in your sub domain

Second: Pass query string to your sub domain and use it as session there

Suppose your sub domain is test.domain.com the pass query from domain.com like this

test.domain.com?query=XXXXX and in test.domain.com on page load event

Session["abc"]=Request.quesryString["query"];

If you have IIS infrastructure, you can share session state between servers. Look here: http://dotnetcodr.com/2013/07/01/web-farms-in-net-and-iis-part-5-session-state-management/[^].

But I am not sure, this is what you need. It looks like you need SSO (single sign-on). There are several implementations of it, so you should look around. Just as idea:
Enterprise Single Sign-On[^]
Single Sign On (SSO) for cross-domain ASP.NET applications: Part-II - The implementation[^]

Hai,

I am used this below code i get the current session id.but how to pass the user login information to another subdomain.

using System.Web.SessionState;
protected void Page_Load(object sender, EventArgs e)
{
if (Session["UserId"] == null) // Is Shared SessionState Available?
{
string sessionId = this.Session.SessionID;
// The SessionId From Source Website.

SessionIDManager manager = new SessionIDManager();
bool isRedirected; // Get true if cookieless=true and you redirected to the current page.
bool isNewSession; // Get true if a new "ASP.NET_SessionId" cookie will be created.
manager.SaveSessionID(Context, sessionId, out isRedirected, out isNewSession);
// Change sessionId in httpResponse of the current Context

Session["Temp"] = "Some useless data.";
// this operation is neccesary because sessionId read from Request and write to Response

Response.Redirect(Request.Path, true);
// Now redirect to current page to check if shared SessionState is available
}
else
{
// Do something after sharing the sessionStates
}
}

Ok, and have you set up the session database and changed IIS configuration about session state on all those servers/subdomains?

i can't get u..i done this C:\Windows\Microsoft.NET\Framework\v4.0.30319\aspnet_regsql.exe -S . -E -ssadd -sstype c ASPState.
created a ASPState database in my db

Zoltán Zörgő 1-Feb-15 3:31am

What does it mean "you can't"... that is no error message..

[no name] 1-Feb-15 3:43am

i get the current session id and its saved into ASPstate database.when i clicked into another subdomain i wanted to send username and password.but its not working.can u give some example for passing the session id for another domain with the username and password for current section.

Zoltán Zörgő 1-Feb-15 3:51am

You are missing something: as long as those application share the same session state storage, the same session-id will represent the same session state. As session cookies in general are bound to domain on the client, you only need to pass session id when traversing the application boundaries.

k sir,which code i will wrote in destination side for accepting the source session id.

Zoltán Zörgő 1-Feb-15 4:36am

You can use SessionIDManager to set session id. Thus, when you redirect from server or provide a link on client side to the other application, yo need to pass the session id. Like:

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

On the other end use following code to set session id:

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

am using this code in main domain login
Session["SessionId"] = this.Session.SessionID; and also another domain am using your above code but i didnt get the session id

Zoltán Zörgő 3-Feb-15 2:23am

Well, if you don't use what you should, don't expect it to work. Storing session id in session state won't change session id. Why should it?

[no name] 3-Feb-15 4:02am

Sir am using dynamic link so y i can use this code Response.Redirect("http://localhost:43392/PartnerHome.aspx?SessID="
+ Session.SessionID); ? there have any other methods?

Zoltán Zörgő 3-Feb-15 4:26am

This part is ok. But in PartnerHome.aspx you need to change properly the session ID. What do you do there?

[no name] 3-Feb-15 4:46am

Partner Home? u mean another domain aspx page?.there have any other method for sharing the same sessionid?.

Zoltán Zörgő 3-Feb-15 4:52am

Sorry, but if you don't read what I write (even what you write yourself), it is meaningless to write anything else. :(

Sir,its working in local host but its not working in server..

[no name] 3-Feb-15 0:41am

I am using dynamic link.when i click that link its redirect to another sub domain.so how to pass the session id through programitically

[no name] 11-Feb-15 6:05am

Its working in local host but its not working in server

Zoltán Zörgő 11-Feb-15 7:51am

Than your servers are not properly configured to user the same session store.

[no name] 11-Feb-15 23:00pm

How can i config the server?

[no name] 11-Feb-15 23:54pm

Another problem is i was login in different user but saved in same session id..what its happen?

Zoltán Zörgő 12-Feb-15 2:30am

Sorry, this is the farest point I can go with you from distance. I can't see your screen, I can't debug instead of you and I can't read documentation for you.
