Abstract

A technique for improving throughput of a gateway interface includes: a client, e.g., a wireless client, forwarding a request to a server via the gateway; determining in the server whether the requested content has been validated, and if so, setting a predetermined header to “validated” and forwarding the requested content to the gateway, and if not, either setting the predetermined header to “not validated” or not setting the predetermined header, and forwarding the requested content to the gateway. The gateway determines whether the predetermined header of the forwarded content has been set to “validated,” and if so, forwards the requested content to the client after encoding the validated content, and if not, validates the content and then encodes the validated content and forwards it to the client. In this way, the gateway does not have to needlessly validate requested content which had already been validated.

Claims12

Dependent claims

A method of improving a throughput of a wireless gateway interface comprising the steps of:

(a) receiving a request for content from a mobile client;
(b) determining whether the requested content has been validated against document type definition (DTD), where the DTD defines rules for markup language syntax;
(c) if the content has been validated against the DTD, setting a predetermined header to “validated” and forwarding the requested content to the wireless gateway;
(d) if the content has not been validated against the DTD, either setting a predetermined header to “not validated” or not setting any validation header, and forwarding the requested content to the wireless gateway;
(e) determining in the wireless gateway whether the forwarded requested content includes the predetermined header that has been set to “validated;”
(f) if the content includes the predetermined header that has been set to “validated,” forwarding the requested content to the mobile client from the wireless gateway;
and
(g) if the content does not include a header that has been set to “validated,” validating the content against the DTD and then forwarding the content to the mobile client from the wireless gateway.
