Question

Reading Classic ASP Cookies in .Net

Asked by: strickdd

I am having trouble writing a cookie in classic ASP and actually reading it in .Net. The code I am using is below. I have stepped through the code in .Net and only the standard "ASP.NET_SessionId" cookie is in the "cookies" object.

I have looked at the cookie through the WebDeveloper extension for firefox and here is what it gives me:

Name      ASP.NET_SessionId
Value      avvpc455trlg2u55jpmiyx45
Host      localhost
Path      /
Secure      No
Expires      At End Of Session

Name      ASPSESSIONIDQSRAADTQ
Value      JEHLGCNANDJNHACEOCFPJDEP
Host      localhost
Path      /
Secure      No
Expires      At End Of Session

Name      AdminLogin
Value      %7B9CA9E4E2%2DBAC3%2D453D%2D8927%2DB9007CCC98F5%7D
Host      localhost
Path      /
Secure      No
Expires      At End Of Session

Any idea why .Net won't ready in the AdminLogin cookie?

//C#.Net Code
public static string GetCookie()
{
	//Check the cookie
	HttpCookieCollection cookies = System.Web.HttpContext.Current.Request.Cookies;
	for (int i = 0; i < cookies.Count; i++)
	{
		if (cookies[i].Name == "AdminLogin")
		{
			return cookies[i].Values["GUID"];
		}
	}
	return "none";
}
 
'ASP Code
Function UpdateCookie(GUID)
	Response.Cookies("AdminLogin") = GUID
	Response.Cookies("AdminLogin").Path = "/"
End Function

strickdd,

I haven't had to do this from ASP.NET but I have run into this with other server languages (and cookies from ASP).  Hopefully the comment above will have what you need.  Otherwise you may need to try to manually "parse" the cookie ASP.NET gets.  I am not an ASP.NET expert so I don't know the specifics for sure or if this will work but basically you get the HTTP_COOKIE variable from the server and manually process it.  I can help with details if you do need to use this method or have a question.

Let me know if you have any questions or need more information.

Thanks for the replies. I was able to figure out the issues that I was having for this problem. I am going to look more into what VS1784 posted to hopfully make my code a little better and more secure. Since this was a fairly major production issue I had to do the quickest thing I could to get it working and didn't have time to look into his/her solution.

What I ended up needing to change was VERY simple, see code below:

//C#.Net Code
public static string GetCookie()
{
    string cookies = "";    
    try{
        cookies = System.Web.HttpContext.Current.Request.Cookies["AdminLogin"];
    }
    catch
    {
       //Cookie doesn't exist
    }    
        return cookies;
        
}
 
'ASP Code
Function UpdateCookie(GUID)
        Response.Cookies("AdminLogin") = GUID
        Response.Cookies("AdminLogin").Path = "/"
End Function
