Need to prevent concurrent minify processing #122

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
1. Invalidate the cache on a very busy site (100+ req/s)
2. The first request will minify the files and re-save the cache (hey, 
great).
3. If this takes a second, 99 other requests will also trigger calls to 
minify the file (potentially bad).

Minify's cache system should use a lock to allow only the first request to 
rebuild the cache, while serving the stale resource in the meantime. At 
the proxy level, Squid calls this "Collapsed Forwarding". http://tr.im/q6DO

I have a rough PHP implementation I can borrow from here: http://
