secure_token_token_last_modified

The secure_token_token_last_modified directive is part of the Secure Token Module for NGINX, which is designed to enhance the security of content delivery networks (CDN) by generating secured tokens for accessing protected resources. This directive specifically allows users to configure the last modified timestamp for the tokens generated, effectively helping manage token validity. This last modified time can be essential in validating the token against the content modification time, ensuring that users receive up-to-date and authenticated content based on their request.

When using this directive, it can be placed within various contexts such as http, server, or location, offering flexibility in its application across different server configurations. The parameter to be specified for this directive is a timestamp, which can be a specific time or a relative time based on the current system time. This helps in scenarios where content might change often, and the system needs to ensure that the tokens being generated reflect the latest state of the resource.

One of the critical usability aspects of this directive is its integration with other token-related directives such as secure_token_expires_time and secure_token. When properly configured alongside these directives, it tightens the security around how tokens are generated and validated, while also managing how long these tokens are considered valid based on the last modified timestamp.
