"Nginx's limit_rate
function limits the data transfer rate of a single connection."

e across those connections. Nginx's limit_rate

series of files which don't necessarily exist when they access your

Has anyone considered the problem of legitimate UAs which request a
series of files which don't necessarily exist when they access your
site? Requests for files like robots.txt, sitemap.xml,
crossdomain.xml, apple-touch-icon.png, etc could quickly cause the UA
to exceed the limit-req burst value.
