It’s just data

Getting the Word Out

Dare Obasanjo: At this point I'd like to note that HTTP provides two mechanisms for web servers to tell clients if a network resource has changed or not. The basics of this mechanism is explained in the blog post HTTP Conditional Get for RSS Hackers which provides a way to prevent clients such as news readers from repeatedly downloading a Web document if it hasn't been updated.

The functionality is clearly there in HTTP.  The word is clearly not getting out to everywhere it should be.


I can't change the world, but these two actions I can take.
