Writing a cookie file

I'm wondering if it's possible to generate a cookie and save it in a text file. The requirement is to generate a cookie for any domain not only that you own. So far I identified the parameters required to generate a "valid" cookie. Here is a good blog article describing that format.

Writing it should be simply a matter of writing a text file in this format. But for advanced, This library allows you to manipulate add, delete, update, Netscape Cookie File eg.

On the other two routes instead we print the request's cookies:. In another terminal, if we make connection with the root route we can see the cookie in Set-Cookie :. What that means? Cookies are scoped by path. A cookie with a given Path attribute cannot be sent to another, unrelated path, even if both path live on the same domain. The value for the Domain attribute of a cookie controls whether the browser should accept it or not and where the cookie goes back.

Give it a second to spin up. Open up a browser's console before opening the links to see the result in the network tab. Here the cookie originates from serene-bastion There's no other choice for the browser to reject this cookie.

Chrome for example gives a warning Firefox does not :. They are on the same domain, but the subdomain is different. Again, the browser rejects this cookie as well:. I used Nginx here to show you there are various ways to set a cookie. The fact that a cookie is set by a web server or by the application's code doesn't matter much for the browser.

Here the browser will happily accept the cookie because the host in Domain includes the host from which the cookie came. Also, the cookie travels back with any new request against valentinog. Here the cookie comes from serene-bastion What should the browser do here? You might think that serene-bastion Instead, it rejects the cookie because it comes from a domain included in the Public Suffix List. The Public Suffix List is a list maintained by Mozilla, used by all browsers to restrict who can set cookies on behalf of other domains.

When Domain is omitted during cookie creation, the browsers defaults to the originating host in the address bar, in this case my code does:. When the cookie lands in the browser's cookie storage we see the Domain applied:. So we have this cookie from serene-bastion Where this cookie should be sent now? To recap, the browser uses the following heuristics to decide what to do with cookies by sender host here I mean the actual URL you visit :.

Takeaway : Domain is the second layer of permissions for cookies, alongside with the Path attribute. Cookies can travel over AJAX requests.

Consider another example with Flask where we have a template, which in turn loads a JavaScript file. Here's the Flask app:. As expected the cookie lands in the browser's Cookie storage. Also, let's tweak our JavaScript code so that we make another Fetch request after getting the cookie:.

In the browser's console you should see an array of cities. Also, in the Network tab of the developer tool you should see a header named Cookie , transmitted to the backend over the AJAX request:. This cookie exchange back and forth between frontend and backend works fine as long as the frontend is in the same context of the backend : we say that they're on the same origin.

That's because by default, Fetch sends credentials, i. Consider a different situation where the backend runs stand-alone, so you have this Flask app running:.

Now in a different folder, outside of the Flask app, create an index. To create a cookie for my site, I write. The whole entry is supplied as one quoted String with segments set apart with semicolons — first the name-value pair, then the expiry date in the correct format, and finally the path.

This syntax is fixed, and you shouldn't go rearranging the elements. Write this entry now. To test out the cookie's contents, we can use a simple script like.

Which will yield this result. You may see another value in there too, which is used by our Stylesheet-switcher. Now we can write another entry to the cookie, using a different name, as so:.

Checking on the cookie's contents now, we can see that our first value is still in there. Had we used the same name, the first value would've been overwritten; but since we used a different name, the new entry has been added in with the first. Erasing cookie entries is easy — just set a new value and give an expiry date before today, as in. You can also give the entry an expiry date of -1 , and it will be erased immediately.

Erase test values 1 and 2 now, if you have the heart. To easily tinker with cookies ourselves, we'll be using some great scripts which were originally coded by » Scott Andrew.
