As some of you know, I am in the midst of a blog series on REST in WCF. Further, I have been hard at work on a series of screencasts on the same subject (in conjunction with Ron Jacobs). My colleague Tim Heuer relayed to me that I didn’t have a single post that we can point a person to that provides links to all of the posts and screencasts. I will keep this post updated with all of the info:

Standard fare for most dynamic data and the way most everybody would tell you to do it.
Only thing is that it scales like a dog.
The thing is that holding all the weather of the entire globe in memory, well, takes a lot of memory. More than is reasonable. In which case, there’s a fairly decent chance that a given request can’t be served from the cache, resulting in a query to the database, an update to the cache, which bumps out something else, in short, not a very good hit rate.
If we were able to make our clients in London perform an HTTP GET on http://weather.myclient.com/UK/London then we could return headers in the HTTP response telling the intermediaries that they can cache the response for an hour, or however long we want.

Instead of getting hammered by millions of requests a day, the internet would shoulder easily 90% of that load making it much easier to scale. Thanks Al.
