Techniques are described for managing preloading of data for client computing systems. A client computing system may provide one or more persistent data storage caches on local storage, such as to support a particular software program executing on the client computing system (e.g., a Web browser program, with the persistent data storage cache designed to store browser cookies and other data for later access by the Web browser program). Additional data may be stored in such a persistent data storage cache by preloading those data groups before they are requested by the client computing system (e.g., based on interactions of a user of the client computing system with an executing program on the client computing system). Particular data groups to preload may be selected in various manners, including to provide a specified type of minimum functionality to a client computing system based on the preloaded data groups.

Managing preloading of data on client systems

A system, method, and computer-readable medium for request routing based on client location information are provided. A content delivery network service provider receives a DNS query from a client computing device. The DNS query corresponds to a resource identifier for requested content from the client computing device. The content delivery network service provider transmits an alternative resource identifier in response to the client computing device DNS query. The alternative resource identifier is selected as a function of client location information. The client location information is obtained from information corresponding to a mapping of at least partial IP addresses to known locations. 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 or transmit another alternative resource identifier.

Request routing utilizing client location information

Techniques are described for managing cached data in a network environment. In one example, the techniques include receiving a client request for a data group, determining that a cached copy of the requested data group that is stored in the persistent cache storage is no longer valid relative to a current copy of the data group stored at a remote data source system, obtaining from the remote data source system information about differences between the cached copy and the current copy and instructions associated with the identified differences, modifying, by the configured server computing system, the cached copy to include the identified differences in accordance with the received instructions, and providing, by the configured server computing system, the modified cached copy of the requested data group to the client in response to the client request.

Managing cached data in a network environment

A system, method, and computer readable medium for managing network storage provider and CDN service providers are provided. A content broker component obtains client computing device requests for content provided by a content provider. The content broker processes the client computing device requests and determines whether a subsequent request for the resource should be directed to a network storage provider or a CDN service provider as a function of the updated or processed by the content broker.

Managing content delivery network service providers by a content broker

Described herein are techniques for initiating item fulfillment at least partly in response to the users performing gestures on touchscreens of client devices. For instance, a user may operate a client device that renders content associated with an item offered by an offering service. The user may thereafter request to acquire the item by performing a gesture on a touchscreen of the client device. The offering service may receive the request and a representation of the gesture and, in response, may determine whether or not to initiate fulfillment of the item at least partly with reference to the received representation of the gesture.

Acquiring items using gestures on a touchscreen

A system, method and computer-readable medium for request routing based on prioritization and load information are provided. A client request processing a resource identifier for requested content transmits a DNS query to a content delivery network service provider. Based on a content provider identifier included in the DNS query, a receiving DNS nameserver determines a selection from a hierarchical organization of POPs and the relative capacity for a selected POP to process a subsequent request for resources. Based on the processing of the prioritization information and load information, the receiving DNS nameserver resolves the DNS query.

Request routing utilizing point of presence load information

Techniques are described for managing data transmissions between computing systems based at least in part on using a streaming transport protocol. At least some such data transmissions may be performed using HTTP, with one or more underlying transport protocols used to implement the HTTP-based data transmissions. HTTP-based data transmissions performed using an underlying streaming transport protocol, for example, may send data without performing error detection for reliability and without ensuring ordered delivery of the sent data. In addition, one or more HTTP-based data transmissions may be initiated using an underlying streaming transport protocol, but subsequent data transmissions may switch to using a different underlying transport protocol (e.g., TCP) or different transmission technique that is performed without using data streaming.

Managing data transfer using streaming protocols

Systems and methods for managing requesting routing functionality associated with resource requests for one or more resources associated with a content provider are provided. The request routing functionality can correspond to the processing of domain name service ('DNS') requests for resources by computing devices and the resolution of the DNS requests by the identification of a network address of a computing device that will provide the requested resources. Based on the processing resource requests initiated by a client computing device, a CDN service provider can obtain performance information from client computing devices and correlate the performance information into a prioritized list for classes of client computing devices. The prioritized list can be utilized in resolving subsequent DNS queries.
