Abstract: The present disclosure provides a generating method and a system for redirecting URL, a redirecting server, a resolving method and a system for resolving a domain-name resolution request, a DNS server, a 302 redirecting method that supports HTTPS, and a network system. A client terminal sends a first HTTP request. The redirecting server specifies a content server, convert an IP address of the content server to a prefix of a redirecting domain name, uses a service domain name as a suffix of the redirecting domain name, combines the redirecting domain name and a URL in the first HTTP to form the redirecting URL, and sends the redirecting URL to the client terminal. The client terminal requests for resolving of the redirecting domain name. The DNS server recognizes a domain name in the domain-name resolution request and performs an inverse converting on the prefix of the redirecting domain name to obtain an IP address of the content server and sends the IP address of the content server to the client terminal.

Abstract: The present disclosure provides a jumping URL generating method, a jumping URL system, and a jumping server; a resolving method and a system for resolving a domain-name resolution request, and a DNS server; and a 302 jumping method and a network system that support HTTPS. A client terminal sends a first HTTP request. The jumping server specifies a content server, convert an IP address of the content server to a prefix of a jumping domain name, uses a service domain name as a suffix of the jumping domain name, combines the jumping domain name and a URL in the first HTTP to form the jumping URL, and sends the jumping URL to the client terminal. The client terminal requests for resolving of the jumping domain name. The DNS server recognizes a domain name in the domain-name resolution request and performs an inverse converting on the prefix of the jumping domain name to obtain an IP address of the content server and sends the IP address of the content server to the client terminal.

Abstract: The present disclosure provides a hypertext transfer protocol (HTTP) scheduling system for content delivery network (CDN), including a central decision-making server, one or more central scheduling servers, and one or more edge scheduling servers. The central decision-making server is configured to generate central decision-making files based on bandwidths and load information of global server clusters. The central scheduling servers are connected to the central decision-making server, the central scheduling servers being configured to execute the central decision-making files, when receiving a client content request, based on a geographic location and a content of the client content request, to select a preferred server cluster and a backup server cluster, and to further return a re-directing address with an address of the preferred server cluster and an address of the backup server cluster to the client. The edge scheduling servers are configured to be in a corresponding edge server cluster.
