After having selected a specific interface based on the service request, a web driver application associated with the service requested in the service request is executed and the selected specific interface is implemented. Then, it is possible to interact with the web driver application, via said specific interface, for providing the service by the service provider.

Abstract: The invention relates to a server and a method for processing requests when several requests compete within the same connection having fixed resources. Conventionally, a priority scheme provides priority values for a priority parameter that express priorities relatively to the priorities of other requests, meaning that a relative allocation of resources is obtained for each request. To achieve a better control on the server by the client, the invention provides specific possible values for the priority parameter that correspond to respective processing profiles. Each processing profile represents specific server behavior for resources allocation, by defining a predefined amount of resources. Thus, the client may choose between using the specific possible values to control the exact amount of resources that will be allocated by the server to process some specific requests, and using the other possible values that correspond to a relative allocation of resources as already done in known techniques.

Abstract: The invention relates to a device and a method for processing requests. In particular, the invention concerns building a dependency tree between the requests received from the client device for prioritizing the processing of the requests by the server device; maintaining a list of requests of the dependency tree in their removal order from the dependency tree while the server device is prioritizing the processing of the requests; and removing a selection of requests from the dependency tree wherein the selection is based on the order of requests in the list.

Abstract: Methods and devices for encoding or decoding messages, each message including a list of information items. The encoding method comprises determining a first list of indexes associated with information items that are already indexed in a local indexing table and a second list of literal values of other information items not yet indexed in said indexing table; encoding the indexes of the first list; binary compressing at least a serialized binary representation of the literal values of the second list; and concatenating the first list and the second list together to obtain an encoded bitstream of the information items. When the messages are sent over a plurality of connections, a global table is shared between the connections to store the indexed items of information; and a local indexing table for each connection associates indexes with references to an entry of the shared global table.

Abstract: The present invention relates to pushing at least one resource associated with a main resource, in response to a request for this main resource.

Abstract: The present invention relates to transmitting a digital resource in a client-server communication system. A disclosed method comprises at a main server device: receiving a request for a main resource from a client device; determining at least one missing secondary resource, wherein the at least one missing secondary resource is at least one resource associated with said requested main resource and missing at the main server device; and requesting a secondary server device to push the at least one missing secondary resource to the client device. Thanks to the push initiated by the main server device, the secondary resources required by the main resource become available at the client device before the latter discovers that they are required to exploit or display the main resource.

Abstract: A method for providing resources to a client, the method being implemented at a server and comprising: making available an indication to the client, indicating that the server is configured to activate a persistent push feature upon authorization of said client, said persistent push feature allowing the server to push resources to the client at any time; and receiving a first message from the client, said first message being based on said indication and allowing the server to continuously push resources to the client.

Abstract: The present invention relates to optimizing pushing of at least one resource associated with a main resource, in response to a request for this main resource, in an intermediary component comprising a cache memory. After having sent a request for a main resource to a second component different from the intermediary component, at least one identifier of at least one resource to be pushed by the second component is received from the second component in response to the sent request. Then, at least one of said at least one received identifier is stored in a list associated with the main resource, the list being stored in the cache memory.

Abstract: The invention concerns a method of exchanging information items, e.g. HTTP headers, between a server device and a plurality of clients, and also concerns such a server device. The server device establishes connections with clients, wherein each connection involves a server-initiated indexing table for the server device to encode information items to be sent over the connection in the server-to-client direction. The method comprises the following steps performed at the server device: obtaining a same single indexing table as the server-initiated indexing table of the connections; in response to receiving a request for data from a client, pushing entries of the table to the client to configure the latter for item exchange in the server-to-client direction, encoding information items associated with the requested data using item indexing based on the table and sending the encoded information items to the client over the connection established with it.

Abstract: There is provided methods for managing streaming over communication networks. Server and client devices share a push policy so that the client device may anticipate data pushes by the server. Anticipation makes it possible to cancel early the sending of some pushed data, therefore reducing bandwidth consumption. The shared push policy may be implicit to both server and client. In embodiments, it is explicitly specified by the server to the client, for example embedded in the Media Presentation Description file or included in a specific HTTP header. The client may also request an update of the shared push policy to meet its own requirements.

Abstract: The present invention relates generally to network quality estimation using HTTP/2 push feature. When network quality estimation is required, a client web application requests a server to enter a probing mode. During the probing mode, the server pushes useful data to the application for the latter to perform the estimation. This avoids wasting bandwidth since the useful data are likely to be used by the application. Furthermore, during the probing mode, the server notifies the application of the push start and the push end of each pushed data. This is one using a web socket established with the application. This makes it possible to overcome the limitations of the application in accessing HTTP/2 features of a client browser. Based on the notifications, the application is able to perform accurate estimations.

Abstract: A method and system for coding/decoding structured documents having structural items that include one or more elements, by generating configuration data including a unified model representative of the structure of a type of element on the basis of at least one structured configuration document. The unified model is modified to improve compression efficiency by grouping at least two transitions between a same starting item and a group of following items into a single transition from the same starting item in a first priority level and assigning a second priority level for one or more transitions within the grouping. A coding/decoding table using the modified unified model associates first and second priority coding values.
