The invention relates to an anti-stealing link system of an internet content delivery network, comprising a user side, a file server website and a file server of the file server website, wherein the user side is used for requesting the file server website to provide a file download link through a browser and initiating a file download request to the file server of the file server website through the returned file download link; the file server website is connected with the user side and is used for returning the file download link in which HTTP (Hyper Text Transport Protocol) User-Agent information of the browser at the user side is introduced; the file server of the file server website is connected with the user side and checks the HTTP User-Agent information in the file download link and User-Agent information in the file download request after receiving the file download request, if the HTTP User-Agent information in the file download link and the User-Agent information in the file download request are consistent, then the request is judged to be a legal request, and file download service is provided for the request; otherwise, the request is judged to be a stealing link, and the file download service is refused to be provided for the request. The invention improves the threshold of the stealing link and effectively protects the right and the interest of the file server website.
