Client-side http translator

Abstract

A network gateway device receives an HTTP compliant request stream from a client device over plural TCP connections, translates the HTTP compliant request stream received over the plural TCP connections into an HTTP non-compliant request stream for transmission over a lesser number of TCP connections, and transmits the HTTP non-compliant request stream to a server device over the lesser number of TCP connections. The network gateway device receives an HTTP non-compliant response stream from the server device over one or more TCP connections, translates the HTTP non-compliant response stream received over the one or more TCP connections into an HTTP compliant response stream for transmission over a greater number of TCP connections, and transmits the HTTP compliant response stream to a client device over the greater number of TCP connections.
