This is 500 ms by default which means the session will be checked if it is free every 500 ms. You can try decreasing the value of LOCKED_ITEM_POLLING_INTERVAL.Make sure the requests are not long running so that if there is a lock on the session variable, it won’t delay other requests for a long time.If you assign True to this parameter, it will block both Read and Write requests. Try to use ReadOnly value for EnableSessionState where possible.Another example: You can store the currently logged in user in cache or database if form authentication class doesn’t have this information For example: Instead of storing the user preferences in the session, you can store them in a cookie. Try to use cookies or database tables instead. Requests OR reducing the delays when there are multiple requests with the same At any point of time, ASP.NET executes only one request with the same session id and the remaining requests are queued behind the request which is getting executed.Īre a few recommendations about avoiding using the same session ID for multiple Multiple requests in the process state with the same ASP.NET Session ID were detected in the dump file.

In order to implement best practices for cookies, add the code lines below into your application.Ĭode-behind file: (new HttpCookie("id", ""))

Consider setting the Secure and HttpOnly properties on the cookie to true.

Consider encrypting information in cookies.

Set expiration dates on cookies to the shortest practical time you can.

Instead, keep a reference in the cookie to a location on the server where the information is. As a rule, do not keep anything in a cookie that, if spoofed, can compromise your application.

For example, do not store a user’s password in a cookie, even temporarily.

Do not store any critical information in cookies.

Destroy sessions upon timeout, logoff, browser close or log-in from a separate location.

Prevent concurrent sessions where possible.

Session cookies should be created with the Secure and HttpOnly attributes set.

HTTPS should be employed for all session based applications handling sensitive data.

Instead, the value should be nothing more than a random string of characters with no meaning other than the session id as a whole.

Ensure that the session id does not contain any additional sensitive data.

This ensures that attackers can’t guess the session id due to some predictability analysis.

Ensure the session id is created in a truly random way.

Ensure the length of the session id is long enough to prevent brute force attacks.

This immediately gives away that the application is ASP.NET and that that cookie contains the session id value. In the case of ASP.NET, the default name is ASP.NET_SessionId.

Reconfigure the default session id name in order to obfuscate the true meaning of the cookie value.
