The maximum upload size feature can be used to specify the maximum size of data that users can upload in a single request. This feature provides a flexible and efficient tool for administrators to limit the size of files to be uploaded and helps improve server performance and reduce operational costs.
Scenarios
Large file upload: In scenarios such as online video uploading, large game distribution, and big data analysis, users may want to upload files whose size exceeds the file size that the server can process. To ensure the successful upload of such files, you can specify a large upper limit.
Protection against malicious upload: For business that requires frequent user interactions, such as social media, forums, and blogs, malicious users may upload large files to consume server resources or launch attacks. To prevent potential risks and improve user experience, you can specify a small upper limit.
Traffic saving: For traffic-sensitive business, such as online education, online conferencing, and API services, the upload of large files may consume a large amount of traffic and thus increase costs. To prevent unnecessary transmission traffic and save costs, you can specify a small upper limit.
