Odoo related Scripts

csrf_token (Odoo)

The technically essential CSRF token (Cross-Site Request Forgery token) is a security mechanism that prevents malicious websites or attackers from performing actions on behalf of an authenticated user. When a user logs in to a website, they receive a CSRF token. This token is usually stored in the form of a cookie or a hidden input in the web form. The CSRF token must be sent with every action or request that the user sends to the website. The website then checks whether the token is correct to ensure that the request originates from a trustworthy sender.

Using the CSRF token ensures that only authorized actions can be performed by a user and that potential CSRF attacks are blocked. The token normally changes with each login or session to further increase security.

More informationen is available on Wikipedia .

__session_info__ (Odoo)

Technically essential for managing Odoo system users (not website users).
