Performing too many requests from the Closure Compiler API you get this error:
Error(22): Too many compiles performed recently. Try again later.
What is the actual/current limit? Is it an hourly limit? A rolling window?
Any documentation on how this is calculated? The only information about this I could find is on this page (search for “abuse”): https://developers.google.com/closure/compiler/docs/gettingstarted_ui?hl=en
There are per minute/per hour/per day caps. This is not currently documented, but I believe it the caps allow a sustained rate of ~1 per minute. In my experience when people run into this problem, they would would be either happier with the command-line tool, or a local compilation server like Plovr or are hitting it by accident (i.e. they don’t realize that they are continuously hitting the web service).
