The invention discloses a method and device for sending a target resource. The method comprises the steps of: in a content distribution network, acquiring a first request for accessing a target website, wherein the first request carries first address information of the target website; encrypting the first address information according to a preset encryption algorithm to obtain second address information; transmitting a second request carrying the second address information and an encryption identifier, wherein the encryption identifier is used for indicating that the second address information is obtained by encrypting the first address information according to the preset encryption algorithm; according to the encryption identifier, carrying out decryption on the second address information according to a preset decryption algorithm corresponding to the preset encryption algorithm to obtain the first address information, and sending a third request carrying the first address information to a source site server of the target website; and sending the target resource of the target website, which is sent by the source site server in response to the third request, to a client. By the method and device disclosed by the invention, the problem of improving correctness of sending the target resource is solved.
