feeds via POST instead of GET
ive been thinkign about the following: why do we not push news(rss, atom, ...) feeds, i.e. Http POST them to everyone intrested instead of everyone intrested GETing the index.rss document every 5 minutes causing a lot of traffic and load.
it would be very easy to implement. especially these days with xmlrpc and REST interfaces everywhere(soemthing the zope world is very used to)
say instead of everyone knowing that index.rss is the file to get if you want the last 20 posts why not have a script/function to call to register your intrest in a certain feed. everytime something is added to this feed they will do a POST of this xml data to all intrested. this would definately reduce the load for the one publishign the post. yes there would be problems to solve like: how do we find out if the other one is not intrested anymore and they forget telling us and so on. but that would be doable.
i think the main reason why push based content distribution hasnt caught on yet(except for smtp(email) and instant msgs) is that it requieres and extra instance of hardware. afterall how is going to receive all the feed infos that joe average is going to miss while hes not connected to the net. he would have to reregister and request all data since the last time he received stuff. it would be intrestign for sites like bloglines as they would not have to crawl all the feeds and for other web apps which provide rss reader capabilities but not for the normal home user. which means it would be neat but not reduce the load as joe is going to cause much more traffic then bloglines&co.
just an idea. maybe this is true for all push based contenten distribution systems. they are potentially nicer and more elegant and effective at what they do but they require extra set up and thats not going to happen in the first phase. when a technology is unknown it has to attract lots of users(while its unknow the scalability problems do not show) and once its big and well know(and getting into all sorts of problems now with load) it will be so in the heads of ppel that they dont want to change it
ps: united utils. just cut our power for an hour! at seven in the evening....how very smart of them. it gets worse. the guys on the road which probably did the power cutting jsut said "there are to many to notify in advance" and didnt give a very good explenation as to why they do this at seven in the evening instead of during the day. c***s
