I have a strange effect on my
site when it is under heavy load.
I randomly
get the properties of other users settings. I have my own implementation of the profile system so I guess I can not blame the profile system itself.
I just need a point
to start debugging from. I guess there is a cookie-value that maps
to an Profile entry somewhere. Is there any chance
to see
how this mapping works?
Here is my profile provider:

This is
how I use it
in the controller:
public ActionResult AddTyreToCart(CartViewModel model)
{
string profile = Request.IsAuthenticated ? Request.AnonymousID : User.Identity.Name;
}
I would like
to debug:
How can 2 users who provide different cookies
get the same profileid?
EDIT
Here is the code for getuniqueid
public int GetUniqueID(string userName, bool isAuthenticated, bool ignoreAuthenticationType, string appName)
{
SqlParameter[] parms = {
new SqlParameter("@Username", SqlDbType.VarChar, 256),
new SqlParameter("@ApplicationName", SqlDbType.VarChar, 256)};
parms[0].Value = userName;
parms[1].Value = appName;
if (!ignoreAuthenticationType)
{
Array.Resize(ref parms, parms.Length + 1);
parms[2] = new SqlParameter("@IsAnonymous", SqlDbType.Bit) { Value = !isAuthenticated };
}
int userID;
object retVal = null;
retVal = SqlHelper.ExecuteScalar(ConfigurationManager.ConnectionStrings["SQLOrderB2CConnString"].ConnectionString, CommandType.StoredProcedure, "getProfileUniqueID", parms);
if (retVal == null)
userID = CreateProfileForUser(userName, isAuthenticated, appName);
else
userID = Convert.ToInt32(retVal);
return userID;
}
And this is the SP:
CREATE PROCEDURE [dbo].[getProfileUniqueID]
@Username VarChar( 256),
@ApplicationName VarChar( 256),
@IsAnonymous bit = null
AS
BEGIN
SET NOCOUNT ON;
/*
[getProfileUniqueID]
created
08.07.2009 mf
Retrive unique id for current user
*/
SELECT UniqueID FROM dbo.Profiles WHERE Username = @Username
AND ApplicationName = @ApplicationName
AND IsAnonymous = @IsAnonymous or @IsAnonymous = null
END
