Introduction to CSP and block-all-mixed-content
Hello friends! Today we want to talk about Content Security Policy, also known as CSP. This technique can help you enhance the security of your website and prevent various attacks. One of the features of CSP is blocking mixed content, which can pose significant risks for websites and users.
Now, let's move on to the concept of block-all-mixed-content. When you enable this setting for your CSP, all HTTP content being loaded within an HTTPS page will be blocked. This means that if your website is running on HTTPS and attempts to load HTTP content, this content will not be displayed whatsoever.
The goal of this action is to protect user data and information. Thus, using block-all-mixed-content, you can ensure that users only see secure and encrypted content. This greatly increases the credibility and security of your website.
It will certainly occur that to activate this feature, certain tasks need to be performed. You can easily add it to your HTTP headers. In the following, we will review how to add it. So let's take a practical example and see how this task is accomplished.

Content-Security-Policy: block-all-mixed-content
