Check cookies in asp.net

I want to check if a user has cookies enabled. Most solutions involve: 1. creating a cookie 2. redirect the user to a custom page or the same page. 3. Read the cookie.

The issue I have is in the 2nd step. Should I use a query string while doing a response.redirect so that in the next trip I know the cookie has already been set and that I should try to read it? What if the user hard codes the URL(along with that query string) in the browser, while accessing the website? Also, if I find that the cookies are enabled and I set a session variable to say that cookies are enabled on this browser, so dont check again in that session. Is that OK? If session is available, is that a good enough indicator that cookies are enabled?

I want to minimize these double trips to each page for checking cookies.

As per my knowledge I know Two ways to check whether browser enables/accepting cookies

  1. By using "Request.Browser.Cookies"

  2. By using Javascript/Jquery

Example:

 if (Request.Browser.Cookies)
 {
       Response.Write("Welcome To Hello World Cookies Accepted by the browser");
 }
 else
 {
                Response.Write("Good Bye To Hello World. Cookie diabled in your browser. Enable cookies and Try again... Cool..");

 }

I would use javascript to make an asynchronous request and check to see if the cookies that were set were handed back in this request.

instead of using this technique which involves multiple steps and pages, and extra waiting time for the enduser, can't you just use the HttpBrowserCapabilities class? This particular class has a Cookies property:

HttpBrowserCapabilities.Cookies Property

Never pass a querystring. You already hinted at it above, but what if some trickster figures our the url and decides they want to pass their own querystring?

If the user has cookies set up, you can set the session and check that. Always check the session.
