Feature | Description |
IPv6 is introduced to solve the pain point of IPv4 address exhaustion, which hinders Internet development. Edge Security Acceleration (ESA) has always committed itself to the robust and sustainable development of Internet technologies. To this end, ESA enables the IPv6 feature for all websites free of charge. You can use IPv4 or IPv6 addresses to access networks based on your business requirements. After you enable IPv6, IPv6 clients can access ESA over IPv6. When ESA accesses the origin server, ESA carries the IPv6 information. | |
If you want your origin server to allow WebSocket requests whose URLs begin with | |
gRPC is an open source high performance Remote Procedure Call (RPC) framework that is developed based on HTTP/2. Using the protocol buffers (Protobuf) messaging format to serialize structured data, gRPC can connect services across languages and platforms and allows you to request a service from a remote server the same way you request an on-premises application. gRPC can also help users reduce bandwidth usage and network latency. | |
If you turn on the Add Visitor Location Headers switch, ESA retrieves content from the origin server with the custom header ali-ip-country included. This header specifies the geographical location of the client. | |
If you turn on the Add "ali-real-client-ip" Header switch, ESA includes the custom header ali-real-client-ip in origin requests to specify the real client IP addresses. | |
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. |
