Someone told me that there is a way for the browser to say to the web server, send me only the parts of the web page I request. For example, send me everything but the flash and images. Being a browser wuss I thought the web server just sent everything and the browser decided whether to display it or not. That would mean the data already was transferred over the expensive sat link incurring the data costs. scott
Just wanted to clear one point up... The web is *not* a "push" model; it's a "pull" model. The HTML document is nothing but a text document which has references to other elements that are available to the browser, should it choose to request them; but it is incumbent upon the browser to request each and every one of those other elements from the server before they are transferred. The server will not send something that was not first requested by the browser. It's misunderstandings like this that make content providers twitch every time an eyeball network says "well you're *sending* all this data at my network" -- absolutely nothing is being sent that was not explicitly requested by the browser first. ^_^; Thanks! Matt
