Abstract: A contents delivery system and method, a web server and a contents provider DNS server of the contents delivery system are provided. A web server or a DNS server of a contents provider determines whether a client is located in proximity to the web server, dynamically selects a server which will provide a page embedded object and provides the page embedded object from the selected server to the client. Accordingly, users can easily use contents and the contents provider can promote qualitative improvement of service.

Abstract: A contents delivery system and method using object redirection, and a GSLB switch thereof are provided. When a client requests a web server to provide a page embedded object, the web server embeds the URL representing the position of the object in an HTTP 302 redirection message and transmits the HTTP 302 redirection message including the URL to the client. A GSLB switch corresponding to the URL transmits the IP address of a specific host server selected from at least one host server storing the object to the client. Accordingly, load of the web server decreases and flexibility in change of a CDN solution is secured.
