![]() ![]() Now that you know about their history, let's take a quick look at how cookies are used to create stateful sessions on the web. Lou took the magic cookie concept and applied it to the online store, and later to browsers as a whole. They're "magic" because the data in the cookie is often a random key or token, and is really just meant for the software using it. To solve this, Lou turned to an idea that was already pretty well known among programmers: the magic cookie.Ī magic cookie, or just cookie, is a bit of data that's passed between two computer programs. Also, they wanted everything to work without customers having to sign in first. MCI requested for all of this data to be stored on each customer's own computer instead. This meant that people had to create an account first, it was slow, and it took up a lot of storage. Lou Montoulli, a developer at Netscape in the early 90s, had a problem – he was developing an online store for another company, MCI, which would store the items in each customer's cart on its servers. That would be super frustrating, wouldn't it? A lot of developers thought so, too, and found different ways to create stateful sessions on the web. It would ask you to enter in your email address and password again, check them, then send over the data to render the new page. The server checks your login information, and if everything looks good, it sends the data needed to render the page back to your browser.īut if LinkedIn was truly stateless, once you navigate to a different page, the server would not remember that you just signed in. You enter that information in and your browser sends it to the server. The process is largely the same as the one above, but you're presented with a form to enter in your email address and password. Now imagine that you need to sign in to a website to see certain content, like with LinkedIn. You can still see this today with simple websites – you type in the URL to the browser, the browser makes a request to a server somewhere, and the server returns the files to render the page and the connection is closed. According to Wikipedia, its a stateless protocol because it "does not require the HTTP server to retain information or status about each user for the duration of multiple requests." HTTP, or the Hypertext Transfer Protocol, is a stateless protocol. In this article, we'll go over the history of cookies, how they work, how to use them in JavaScript, and some security concerns to keep in mind. Whether you know it or not, cookies are everywhere, and for better or worse, they completely changed the way we use the web. After researching this I got the impression that the underlying urllib3 library requires extra proxy information.Have you ever wondered how you can sign in to a website once and remain signed in, even if you close your browser? Or added an item to your shopping cart without signing in at all? Problem is, if I specify nothing but the url in the requests get/post method, I get ValueError: check_hostname requires server_hostname error. To make http(s) requests I use the requests library. ![]() Within that response function I want to make an http(s) request to an unrelated endpoint. ![]() Let's say I have an addon that modifies a response from specific endpoints, like the one provided in the documentation example: ![]()
