An edge server of a content delivery network (CDN) can serve as a proxy for an origin server. The edge server can remove distinguishing characteristics of the origin server. As a result, an end user system may be prevented from blocking content from the origin server based on the distinguishing characteristics. Additionally or alternatively, the edge server can encrypt a portion a uniform resource locator (URL) referencing the origin server so that the clear text of the URL does not follow a recognizable pattern. The path can be decrypted by the edge server when the edge server communicates with the origin server to retrieve the content from the origin server.
