302 REDIRECTING METHOD, URL GENERATING METHOD AND SYSTEM, AND DOMAIN-NAME RESOLVING METHOD AND SYSTEM

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. The client terminal sends a second HTTP request containing the redirecting URL to the content server; and sends an IP generated by resolving and in correspondence of the first HTTP request to the client terminal.
