Method and arrangement for retrieving object data. A method performed by a communication network node 204 of enabling retrieval of an object, such as an element of web-page, is provided. The location of the 5 object is defined by a Uniform Resource Locator, URL, in a distributed caching system 200. The method comprises restructuring 2:1 the URL into a format being readable by a DNS server, and sending 2:2 a DNS query comprising the restructured URL to the DNS server 206. Furthermore, the method comprises receiving 2:3 an IP -address of a cache 202a, 202b, 202c in the distributed caching system 200, wherein the cache 202a, 202b, 202c stores the object. Moreover, the method comprises sending 2:4 an http -get request for the object to the cache 202a, 202b, 202c having the received IP-address, and receiving 2:5 an http-response comprising the object from the cache 202a, 202b, 202c. By providing DNS-servers with information of objects' locations, and restructuring URLs into a format which is readable by the DNS-servers, end users may make use of the fast looking up capability of the DNS-servers for finding objects' locations. |
