Description: A pre-signed URL allows temporary access to a resource in a web environment, facilitating permission management and security in resource distribution. These URLs are generated by a server and contain information that allows users to access a specific resource without needing to authenticate each time. The main feature of a pre-signed URL is its temporary validity; that is, it can only be used within a specified time frame, minimizing the risk of unauthorized access. Additionally, these URLs can include parameters that limit access to certain actions, such as reading or writing data, providing further control over how resources are used. In the context of web applications, pre-signed URLs are particularly useful for applications that require secure and efficient resource sharing, such as in cloud storage services or applications handling sensitive data. Their implementation allows developers to offer a seamless user experience while ensuring that resources are protected from unauthorized access.
