Since all packets for connection establishment and close are handled in the TwoB proxy, our scheme eliminates the packets in this category as illustrated in Fig.
Since the TwoB proxy maintains a local DNS cache and exploits HTTP persistent connections with web servers, these features help to offset the increased WAN delay to the measured web loading time.
Now, we measured the effect of appending static header fields in the TwoB proxy.
Although our browser architecture can improve web browsing, it is important to find the best configurations of our TwoB proxy and the browser front-end.
The queueing delay of an HTTP request is the time between when the request arrives at the queue and when the request is transferred to the TwoB proxy.
In more detail, our approach tries to reduce latency associated with WAN by exploiting HTTP persistent connections with web servers and by maintaining DNS cache inside the TwoB proxy server.
