markdown\_contentname: markdown | content: Using Open Graph to optimize sharing on social networks has become commonplace. You have already shared an article with the wrong image, or a spelling error in the title ... In these cases, you quickly delete your publication, you correct the error and then try to post it again and ... your fault is still there! Indeed, once you have shared a link (or just tried to share it without actually finalize the action to see how it will be visualized), a cache is automatically generated in the Open Graph of the social network on which you are.
