Imagine you have a magic token that only you and your best friend know. 
Every time your friend wants to give you a gift, they have to include 
this special token with the gift. When you receive the gift, you check 
if the token matches the one you gave to your friend. If it matches, 
you know it's a genuine gift from your friend.

In the same way, when you visit a website, the website gives you a 
secret token, just like the magic token. Then, when you fill out a 
form on that website and submit it, the form includes that secret token. 
When the website receives your form, it checks if the token you 
sent matches the one it gave you. If they match, the website knows 
the form was genuinely submitted by you.

This secret token is called the CSRF token in Django. It's a way for the 
website to make sure that the form submissions it receives are from 
the same person who loaded the form. It helps prevent bad people from 
tricking you into submitting forms without your knowledge or permission.

So, the CSRF token is like a secret code that ensures the website can 
trust the forms you submit. It's an important security measure to keep 
you and your information safe when interacting with websites.

Also Remember:
  In Django, the CSRF token is different for each user session but 
  remains the same within a session.

When you first visit a website, Django generates a unique CSRF token for 
your session and includes it in the HTML form. This token is stored in 
your browser's cookies or session storage.

Each time you submit a form on that website during your session, the 
same CSRF token is sent along with the form data. The server checks if 
the submitted token matches the one stored in the user's session. If 
they match, the form submission is considered valid.

So, the CSRF token is unique to your session but remains the same 
throughout that session. It helps prevent CSRF attacks by ensuring 
that the form submissions originate from the same user who loaded the 
form.

Cross Site Request Forgery protection¶
The CSRF middleware and template tag provides easy-to-use protection against
Cross Site Request Forgeries. This type of attack occurs when a malicious
website contains a link, a form button or some JavaScript that is intended 
to perform some action on your website, using the credentials of a logged-in 
user who visits the malicious site in their browser. A related type of attack,
‘login CSRF’, where an attacking site tricks a user’s browser into logging into
a site with someone else’s credentials, is also covered.

The first defense against CSRF attacks is to ensure that GET requests
(and other ‘safe’ methods, as defined by RFC 7231#section-4.2.1) are
 side effect free. Requests via ‘unsafe’ methods, such as POST, PUT,
 and DELETE, can then be protected by following the steps below.
