I'd be surprised if this was possible- and this is only me thinking logically and not talkin from experience with this kind of thing but if you think about, whenever you do a test speed for your broadband (which i used to do often when we got new SDSL), you must notice it takes a while to test the speed and collaborate the numbers and then plot it against a callibrated set of results and thus map out the users speed from there?
This would be annoying for some people... BUT on the other hand there may be part of a web log that has some info on a users speed and might be able to be extracted on the fly, i'm not sure but they're the two different ways i'd
look at it.
Thanks for the insight.... I know that Yahoo Maps does it...
what I am thinking is if there is some way do have the site blindly load a script with say a 10kb file.... then if the the upload took longer than (x amount of time) it would direct to the low-speed site.
I have the concept, but no idea how to cod it, or if it's even possible.
How about using JS to detect how long it takes for a page to load, so if its a 10kb page then you can calculate the time from that.
don't know anything about JS though so don't ask me .
