<font color="#000000"><font size="2"><font face="trebuchet ms,sans-serif">I am sure there is a better way but here is a suggestion. Use the rate limit to identify when there is more than one connection per minute and redirect that to the cache, if it doesnt hit that limit then you can use the cache_bypass. Not sure if this would work hope someone can confirm, but a thought.<br>

what is the easiest way to force all request to be satisfied from the cache for lets say a minute? What I'm basically trying to do is to rate-limit the requests to the proxy upstream so that the upstream server will see no more than for example one request per minute for a specific url.<br>
<br>
