Fix typos
I'm really sorry for the poor Camilleri :) Wu Ming's "Q" is really worth reading though URL(novel)
What, no Eco? :)
No warnings
There are six lines that are marked as too long.: It might make sense to break these into two lines: and add text saying "Shown on two lines for clarity" or something.
3 fixed ;)
NAME Can this be closed now?
Looks good - thanks for the literary recommendations; I already followed inspector Montalbano's deeds, but Q looks an interesting addition... if/whenever my son gives me some time to read! :smile:

Discussion:
Servers use quota mechanisms to avoid systems overload, to ensure an equitable distribution of computational resources or to enforce other <del> policies - eg. monetization. </del> <ins> policies - e.g. monetization. </ins> A basic quota mechanism limits the number of acceptable requests in a <del> given time window, eg. 10 requests per second. </del> <ins> given time window, e.g. 10 requests per second. </ins> When quota is exceeded, servers usually do not serve the request <del> replying instead with a "4xx" HTTP status code (eg. 429 or 403) or </del> <ins> replying instead with a "4xx" HTTP status code (e.g. 429 or 403) or </ins> adopt more aggressive policies like dropping connections. <del> Quotas may be enforced on different basis (eg. per user, per IP, per </del> <ins> Quotas may be enforced on different basis (e.g. per user, per IP, per </ins> geographic area, ..) and at different levels.  For example, an user may be allowed to issue:

count once requests like "/books/{id}" <del> count twice search requests like "/books?author=Camilleri" </del> <ins> count twice search requests like "/books?author=WuMing" </ins> so that we have the following counters

The client MUST NOT assume that all its "service-limit" will be restored after the moment referenced by "RateLimit-Reset".  The server MAY arbitrarily alter the "RateLimit-Reset" value between <del> subsequent requests eg. in case of resource saturation or to </del> <ins> subsequent requests e.g. in case of resource saturation or to </ins> implement sliding window policies. 4.

For example, given the rate limiting fields below, a client could decide to wait 10 seconds before following the

This specification does not mandate a specific throttling behavior and implementers can adopt their preferred policies, including: <del> slowing down or preemptively backoff their request rate when </del> <ins> slowing down or preemptively back-off their request rate when </ins> approaching quota limits; consuming all the quota according to the exposed limits and then
