What is cookie less session? How it works?..

Answer / chandra prakash

You can set the cookieless setting to one of the values defined by the HttpCookieMode enumeration,
as described

1)UseCookies - Cookies are always used, even if the browser or device doesn’t support cookies or they are disabled. This is the default. If the device does not support cookies, session information will be lost over subsequent requests,
because each request will get a new ID.

2)UseUri - Cookies are never used, regardless of the capabilities of the browser or device. Instead, the session ID is stored in the URL.

3)UseDeviceProfile- ASP.NET chooses whether to use cookieless sessions by examining the BrowserCapabilities object. The drawback is that this object indicates what
the device should support—it doesn’t take into account that the user may have disabled cookies in a browser that supports them.

4)AutoDetect- ASP.NET attempts to determine whether the browser supports cookies by attempting to set and retrieve a cookie (a technique commonly used on the Web). This technique can correctly determine whether a browser supports
cookies but has them disabled, in which case cookieless mode is used instead.

Answer / shalini

If cookies is not supported then cookieless sessions is
the best option. If you set the cookieless attribute of the
sessionState element to "true" in your web.config, you will
notice that sessions still work perfectly when invoking
your Web methods using the browser interface.Code for using
cookiless session is:(.aspx code)

<html><head><title>Object moved</title></head><body>
<h2>Object moved to <a href='/HttpSessionState/
(l2z3psnhh2cf1oahmai44p21)/service1.asmx'>here</a>.</h2>
</body></html>

Code for using cookiless session is:(aspx.cs code)

[WebMethod(EnableSession=true)]
public bool Login(string user, string pwd)
{
Session["extuser"] = user;
return true;
}

[WebMethod(EnableSession=true)]
public String getUser()
{
return Session["extuser"].ToString();
}
