If they've sent us messages before, we'll specify how many messages we've gotten from them.If you have been following tutorials from this blog you probably know that Twilio uses the webhook pattern in many of its products. If they're a new sender, we'll thank them for the new message. Let's try using session counters to see if a particular user has messaged us before. The code sample below does the latter, using the Session State feature available in ASP.NET. You can store the data directly in a cookie, or you can use a session state management framework. The cookies let you share state across multiple messages allowing you to treat separate messages as a conversation, and store data about the conversation in the cookies for future reference. How cool is that? Twilio will expire the cookies for that conversation after four hours of inactivity, as if the user "closed the browser." Storing Conversation Data This means you can use server-side sessions to keep track of application state between requests. Similarly, SMS messages are independent communications between two parties, so Twilio allows you to tie them together as a logical session via cookies. In web apps, you write a cookie to keep "statefulness" between separate requests from the same browser. For example, you can store a unique cookie for any messages sent between 41 and 41, which will be different than the cookie used between 41 and 41. For Twilio Messaging, cookies are scoped to the "conversation" between two parties - you can have a unique cookie for each To/From phone number pair. Just like in web applications, a cookie is a small file that your application can store on Twilio's servers to keep track of information, such as a username or account. Using HTTP Cookies with Webhooks What is a cookie ? Be sure to check out our Conversations product to see if it's a better fit for your needs.
