US 9,288,261 B2 · Network resource modification for higher network connection concurrence

Abstract

Implementations for network resource modification for enabling higher network connection concurrence are disclosed. An example method includes receiving a request from a client for a network resource having references to objects, and retrieving the network resource from one or more servers. The method further includes modifying the network resource to cause the client to open a greater number of concurrent TCP connections to the network appliance than otherwise would have been opened had the network resource not been modified due to a browser program imposed limit on a number of concurrent TCP connections. The method further includes sending the modified network resource to the client, receiving a plurality requests for the objects from the client over the greater number of concurrent TCP connections, and replying to the plurality of requests for the objects by sending the objects to the client over the greater number of concurrent TCP connections.

Dependent claims

A method for network communications among a network appliance connectable to one or more client devices via a wide area network and one or more server devices via a local area network, the method comprising, at the network appliance:

receiving, from a client device of the one or more client devices via the wide area network, a request for a network resource having a plurality of references to respective objects;
retrieving the network resource from the one or more server devices via the local area network;
identifying based, at least in part, on cache control header information or object type information of each object referenced in the network resource whether that object is a cacheable object;
selectively modifying the network resource by rewriting references for non-cacheable objects identified from the cache control header information or object type information of the plurality of references, to specify one or more different references to the non-cacheable objects to increase a number of concurrent Transmission Control Protocol (TCP) connections to the network appliance that are opened by a browser program of the client device relative to a number of concurrent TCP connections that would have otherwise been opened by the browser program had the network resource not been modified;
if one or more non-cacheable objects have been identified, sending the modified network resource to the client device via the wide area network;
and
if only cacheable objects have been identified, sending the network resource to the client device via the wide area network without modifying the references.

A network appliance connected or connectable to one or more client devices via a wide area network and one or more server devices via a local area network, the network appliance comprising:

one or more processors;
and
mass storage including a routing program executable by the one or more processors to:
receive an initial request for a network resource from a client device of the one or more client devices via the wide area network;
retrieve the network resource from a server device of the one or more server devices via the local area network, the network resource having a plurality of references to respective objects;
identify based, at least in part, on cache control header information or object type information of each object referenced in the network resource whether that object is a cacheable object;
send the network resource to the client device via the wide area network;
receive, from the client device via the wide area network, a plurality of initial requests for the objects referenced in the network resource by the plurality of references;
in response to receiving the plurality of initial requests from the client device, send one or more redirect messages to the client device via the wide area network to cause the client device to issue one or more subsequent requests for one or more of the objects via the wide area network over one or more different Transmission Control Protocol (TCP) connections than one or more initial TCP connections by which the plurality of initial requests were received;
receive one or more subsequent requests for the one or more objects from the client device via the wide area network over the one or more different TCP connections;
and
reply to the subsequent requests for the one or more objects by sending the one or more objects to the client device via the wide area network over the one or more different TCP connections.
