When I posted a news link on Facebook, it generated a preview by its own fetching the details from the url.
Does anybody know what kind of technology or scripting language is used to do this or how it can be done? If anyone can guide me or point me to the direction how can I achieve this using Python on a simple HTML form.
How it can be achieved on simple HTML forms using python scirpt?
Thank you in advance.
