Agent vs. Agent

The phrase User agent or user-agent or UA or browser or client or client application or client software program...all pretty much refer to the same thing. Or maybe not.

How to Build a Better Web Browser

Web browsers are funny things. On the one hand, they’re supposed to be lightweight little programs that just let you view websites, and on the other, they carry the same burdens as operating systems and application suites, trying to provide everything to everyone. Here in this little essay I explain what I know about designing browsers. I’m in the lucky minority of people that have actually designed successful browsers, or parts of them, for any length of time, and with Firefox and Opera in the headlines, and the art of browser design becomes important again, I thought I’d write down some of what I know. Its been years since I was a program manager on the Internet Explorer project, but I’ve maintained interests in the design of navigation and searching systems of all kinds: what follows is a rough summary of what I’ve learned.

Software Features and Changes Needed for Better Viewing

With Netscape, when you first load this page, none of the following links are marked as 'already seen'. IE is very bad on this point: when you load this page, all the links below (internal page A NAME links) are marked as 'already seen'. That is, Netscape tracks internal page jumps; IE doesn't recognize them; in its history tracking, it lumps together all the links for a page as being identical with the overall page as a destination. This is a great example of a basic feature that is very much needed.
