An Access Log is a record that keeps track of all requests made to a server. It typically includes details such as the date and time of the request, the IP address of the user, the requested URL, and the status of the response. This information helps website administrators monitor traffic and identify potential issues. Access logs are essential for maintaining the security and performance of a website. By analyzing these logs, administrators can detect unauthorized access attempts, troubleshoot errors, and optimize server performance. Tools like Web Analytics can further assist in interpreting the data from access logs.
