Master baker tier. Every paragraph earns its place on the tray.
Summary
The article describes a developer's journey to implement CSRF (Cross-Site Request Forgery) protection for the Microdot web framework. Initially expecting to use traditional methods like anti-CSRF tokens, double-submit cookies, and hidden form fields, the author discovered a simpler approach that doesn't require these traditional elements. The article explains this alternative method for CSRF protection that eliminates the need for tokens or hidden fields, making implementation easier while maintaining security.

· 3 pulledWhen I set off to do this work in early November I expected I was going to have to deal with anti-CSRF tokens, double-submit cookies and hidden form fields, pretty much the traditional elements that we have used to build a defense against CSRF for years.
But then I bumped into a new way some people are dealing with CSRF attacks that is way simpler, which I describe below.
A couple of months ago, I received a request from a random Internet user to add CSRF protection to my little web framework Microdot, and I thought it was a fantastic idea.
