Abstract: A system and method for management and processing of resource requests is provided. A content delivery network service provider receives a DNS query from a client computing device. The DNS query corresponds to a requested resource from the client computing device. The content delivery network service provider associates the client computing device with a cluster of other client computing devices. Based on routing information for the cluster, the content delivery network service provider routes the DNS query. The process can further include monitoring performance data associated with the delivery of the requested resource and updating the routing information for the cluster based on the performance data for use in processing subsequent requests from client computing devices in the cluster.

Abstract: A system, method and computer-readable medium for client-side processing of resource identifiers. A client request for content is returned that includes information for generating a request for translation information and a number of embedded resource identifiers. Based on the information for generating a request for translation information, the client generates and obtains translation information and processes the embedded resource identifiers to obtain resources from a service provider.

Abstract: Mobile device users may be tracked either via mobile-signal triangulation or via Global Positioning Satellite information. A mobile device user's recent movements may be analyzed to determine trails or traffic patterns for device user among various locations. Mobile device trail information, either for an individual user or aggregated for multiple users, may be analyzed to determine a next destination for the user. Electronic advertising content, such as advertisements, coupons and/or other communications, associated with the next destination may be sent to the mobile device. Additionally, the identity of the mobile device use may be known and the advertisements or coupons may be tailored according to demographic information regarding the mobile device user. In addition, destinations may be recommended to mobile device users based on the recent locations the users have visited.

Abstract: A system, method and computer-readable medium for request routing. A client request processing a resource identifier for requested content transmits a first DNS query to a content delivery network service provider. The content delivery network service provider transmits an alternative resource identifier in response to the client computing device DNS query. The client computing device then issues a second DNS query to the same content delivery network service provider. The content delivery network service provider can then either resolve the second DNS query with an IP address of a cache component or transmit another alternative resource identifier that will resolve to the content delivery network service provider. The process can repeat with the content delivery network service provider's network until a DNS server resolves a DNS query from the client computing device.

Abstract: Techniques for determining user input on a touch screen of a user device are disclosed. In some situations, the techniques include: receiving information about a user input provided to a touch screen of a user device, the touch screen displaying two or more selectable objects, wherein each of the selectable objects, if selected, initiates a response corresponding to the selection of the object, determining a selectable object among the selectable objects that has a highest likelihood of being an object that a user intended to select with the user input, and providing a response corresponding to a selection of the determined selectable object. In one situation, a selectable object is a button or a hyperlink included in a Web page displayed on the screen of the device, and the response includes content associated with the selected button or hyperlink.

Abstract: Disclosed are various embodiments for detecting unexpected behavior. A path associated with a user is tracked. It is determined whether the path corresponds to at least one intent grouping that in turn corresponds to an expected behavior. Unexpected behavior is identified when the path does not correspond to at least one intent grouping.

Abstract: A system may use search refinements to identify new product trends. These product trends may be associated with attributes or product features that may previously have been available, but are newly of interest to a users. The system may compare search refinements used by users during an earlier time period with search refinements used during a more recent time period to identify search refinements that are used more often during the later time period. Based on this comparison, the system can identify a product feature that is of interest to users during the later time period, but not the earlier time period. The system can then recommend products with the product feature to potential customers. Further, if the product feature was not available during the earlier time period, the system can identify to potential customers that the product feature is newly available in relation to the earlier time period.

Abstract: A web browser is implemented to receive a document from a server. The document may include one or more embedded Uniform Resource Locator (URL) references. The web browser may display the document on a user interface. A user associated with the web browser may determine one or more of the original embedded URL references should be replaced. In response to user input, the web browser may change at least one of the original embedded URL references to a corresponding replacement embedded URL reference and display the document with the replacement embedded URL reference. The web browser may save an association of the original embedded URL reference with the replacement embedded URL reference and subsequently, when receiving the document with the original embedded URL reference, automatically replace the original embedded URL reference with the corresponding replacement embedded URL reference before displaying the document.

Abstract: A system may identify new features of items represented in an electronic catalog by comparing the attributes of items from an earlier time period (e.g., 1 to 3 years ago) with the attributes of items from a later or more recent time period (e.g., today) for a given items classification. By identifying attributes associated with items from the later time period, but not with items from the earlier time period, the system can identify new features associated with the given items classification. In some cases, the system may use search behaviors of users to assess whether such new features are important to users.

Abstract: Disclosed are embodiments configured to detect a quorum of peers in a peer to peer network. In one embodiment, a first peer receives a message originating in a second peer, where the message includes a peer identifier. The peer identifier is stored in quorum detection data in response to determining that the peer identifier is not already present in the quorum detection data. A quorum of the peers is detected based at least in part on the quorum detection data.

Abstract: Disclosed are various systems, methods, and computer-readable mediums embodying programs that are configured to detect a quorum of peers in a peer to peer network. In one embodiment, a first one of a plurality of peers receives a message from one of a plurality of second ones of the peers, the message including at least one peer identifier listed in association with a corresponding at least one property value, where the peers communicate with each other on a peer to peer network. The at least one peer identifier is written in association with a corresponding at least one property value in a memory associated with the first one of the peers when the at least one peer identifier does not exist in the memory. Also, a quorum of peer identifiers existing in the memory that are associated with respective property values that match a predefined criteria are detected, and a predefined action is implemented in the first one of the peers upon detecting the quorum.

Abstract: Paths followed by a plurality of devices are recorded. Devices of the plurality have sent content requests similar to a current content request. Behaviors exhibited by respective ones of the plurality of devices. The respective ones of the paths are grouped into intent groupings. A path followed by a device is assembled. The assembling the path comprises recording a plurality of content requests generated by the device prior to the current content request. An intent grouping matching the path is identified. The intent grouping is associated with an expected behavior. Content calculated to facilitate the expected behavior is identified.
