BlueInk: Last-Modified date…
Most web sites build with a Content Management System (CMS) do not send the correct “Last-Modified” date to the browser. The average CMS (include WordPress which runs this blog) show the current time as the date the page was last modified. The truth, though, is that the average web page or blog entry hasn’t been touched for some time (and certainly not in the last 30 seconds).
BlueInk, however, outputs the date the page was actually modified last. If you view the home page, for example, and click “Tools | Page Info…” (or the like for your specific browser), you’ll see “Modified: 02/13/2008 11:19:30 AM” That is, in fact, the last moment I made a change to that page. Yesterday, though, before we added this marginal but useful feature you would have seen whatever your current date and time are.
So why should I care?
While this may be the first time you’ve ever bothered to look at the page info for a web page, this data is useful to other web sites and web services that may interact with your web site. Search engines would be the first most obvious group of services to perhaps use this info. The growing number of “Web 2.0″ applications and even what are being called “Web 3.0″ or the “Semantic Web” applications could (and likely will) make use of that data.
We hope that our increasing “geekiness” about HTTP, REST, and other web standards will continue to pay off for our users in ways none of us may yet have envisioned. We’ll keep the future in mind.
