To refresh the session cookie from a client web app when it expires, you have a few options based on the information provided in the knowledge sources: 1. Use the login flow with `refresh=true`: You can initiate a login flow with the

refresh=true

query parameter. This will prompt the user to re-authenticate and refresh their session. Here's how you can do it:

https://$<http://PROJECT_SLUG.projects.oryapis.com/self-service/login/browser?refresh=true|PROJECT_SLUG.projects.oryapis.com/self-service/login/browser?refresh=true>

[Kratos Self-Service Flows Documentation](https://www.ory.sh/docs/kratos/self-service/flows/user-login#refreshing-a-session) provides more details on this approach. 2. Use the extend session API: You can call the extend session API from your backend to refresh the session. However, note that as of version 1.3.0, this API will return a 204 No Content response for new Ory Network projects, and the session details will no longer be returned in the response. [GitHub Discussion on Session Extension](https://github.com/ory/kratos/discussions/4132) mentions this change and suggests fetching the session after expiry if you need the updated session details. 3. Implement automatic session extension: You can implement a mechanism to automatically extend the session for active users. This typically involves calling the extend session API from your backend at regular intervals or before the session expires. It's important to note that the specific implementation details may vary depending on your application's architecture and requirements. Additionally, you should consider the

earliest_possible_extend

configuration setting, which limits how soon a session can be refreshed before its expiration. [Session Management Documentation](https://www.ory.sh/docs/kratos/session-management/refresh-extend-sessions#refresh-threshold) provides more information on configuring the refresh threshold. Remember to handle the refresh process securely, especially when dealing with sensitive operations that might require re-authentication.

Certainly! I can provide you with a React code example for checking and refreshing a session. This example is based on the information from the Ory documentation. Here's a React component that demonstrates how to check a session and potentially refresh it:

jsx import { Configuration, FrontendApi, Session } from "@ory/client" import { useEffect, useState } from "react"  const frontend = new FrontendApi(   new Configuration({     basePath: "<http://localhost:4000>", // Use your local Ory Tunnel URL     baseOptions: {       withCredentials: true,     },   }), )  export function SessionCheck() {   const [session, setSession] = useState<Session | undefined>()    useEffect(() => {     checkSession()   }, [])    const checkSession = () => {     frontend       .toSession()       .then(({ data: session }) => {         setSession(session)       })       .catch((error) => {         // The session could not be fetched         // This might occur if the current session has expired         console.error("Session check failed:", error)         refreshSession()       })   }    const refreshSession = () => {     frontend       .createBrowserLoginFlow({ refresh: true })       .then(({ data }) => {         // Redirect the user to the login flow         window.location.href = data.request_url       })       .catch((error) => {         console.error("Failed to initiate login flow:", error)       })   }    return session ? (     <div>       <h2>Session Active</h2>       <p>Session ID: {session.id}</p>       <p>Expires at: {session.expires_at}</p>     </div>   ) : (     <div>No active session</div>   ) }

This example does the following: 1. It uses the Ory SDK (

@ory/client

) to interact with the Ory API. 2. The

SessionCheck

component checks for an active session when it mounts. 3. If a session is found, it displays the session information. 4. If the session check fails (possibly due to expiration), it attempts to refresh the session by initiating a new login flow with

refresh=true

. 5. When refreshing, it redirects the user to the login flow URL, which will prompt for re-authentication. Remember to replace

"<http://localhost:4000>"

with your actual Ory project URL or local tunnel URL. This code is based on the examples provided in the [Ory documentation for checking session status](https://www.ory.sh/docs/kratos/bring-your-own-ui/custom-ui-basic-integration#session-checks) and [refreshing sessions](https://www.ory.sh/docs/kratos/self-service/flows/user-login#refreshing-a-session). Note that this is a basic example and you might need to adjust it based on your specific application requirements and error handling needs.
