One platform that meets your industrys unique security needs. Many HTTP/1.0 browsers and servers were extended (starting around 1996) to support an early, experimental type of persistent connections called keep-alive connections.These early persistent connections suffered from some interoperability design problems that were rectified in later revisions of HTTP/1.1, but many clients and servers still use these earlier keep-alive connections. While in most cases this is the equivalent of setting the idle session timeout to 0, there are cases where you could end up with a shutdown of the Asp.Net worker process - idle timeout or keepalive alike. So it is easily and quickly available and is best suited for web application performance but the main disadvantage is that because all the information is stored on the server side in the same application domain, if we will restart the server all the data will be lost.

So, we now detect if a user session is close to expiry and then present them with a modal that allows them to click a button to keep their session alive. any comma-separated list of HTTP headers [Usually keep-alive only] Indicates that the client would like to keep the connection open. Sometimes you want to keep a session alive only as long as the user is on the site, or until they close their browser. Though documents and application protocols are generally text-based, the resemblance ends there. Keeping a user forcefully logged in for longer than a normal duration Either cut off their session, or don't. Fortunately for us, Android sets the Keep-Alive header by default, which a quick glance at the header fields of a newly opened HttpURLConnection shows.

HTTP persistent connection, also called HTTP keep-alive, or HTTP connection reuse, is the idea of using a single TCP connection to send and receive multiple HTTP requests/responses, as opposed to opening a new connection for every single request/response pair. The second modal is more complicated - the modal blocks further interaction with the page and is only removed upon correct password re-entry.

If the username and password are correct but the user has not been activated then the code returned is -2. HTTP Keep-Alive on Android does NOT just work. An HTTP/1.1 client MAY expect a connection to remain open, but would decide to keep it open based on whether the response from a server contains a Connection header with the connection-token close. I smell two "bad smells" in this approach: First, you should never trust the client. The default keep-alive idle timeout value is 5 seconds, but you can now configure a higher value up to 60 seconds. The Student class is used for the server to send data to the client. Asking for help, clarification, or responding to other answers.
