Abstract: A method and an apparatus of limiting a rate at which traffic is received at an origin server are described. A first request for a resource at an origin server is received at a proxy server from a client device. A first response that includes a refresh instruction, a first refresh time, and a first cryptographic token that is not valid until a first predetermined time is reached is transmitted to the client device. The refresh instruction is to cause the client device to request the resource after the first refresh time has elapsed. A value of a first counter is incremented. As a result of the refresh instruction a second request for the resource is received from the client device. The second request includes the first cryptographic token. Responsive to determining that the first cryptographic token is valid, fulfilling the request.

Abstract: A browser receives a web page that includes a script that is configured to control subsequent requests of the browser for at least the web page and caches a first portion of the web page that includes reference(s) to other web resource(s). A subsequent request for the web page is dispatched to the script which returns the cached first portion of the web page to the browser and a request for the full web page is made. Request(s) are also transmitted for the web resource(s) referenced in the first portion of the web page without waiting for the full web page to be received. When the full web page is received, if the first portion of the page matches the corresponding portion of the full page, that corresponding portion is removed from the full page and the remaining page is returned to the browser.

Abstract: A process for prioritizing content responses executed by a first server in a distributed cloud platform. The first server including processor, and a non-transitory machine-readable storage medium that provides instructions that, when executed by the processor, causes the first server to perform operations including to receive a request for a plurality of content items from a client device, where the proxy server is in a distributed cloud computing platform, receive a first content item of the plurality of content items from an origin server or a cache, determine a priority scheme for ordering the plurality of content items, where the priority scheme is specific to the plurality of content items and is derived from analysis of a first content item from the plurality of content items, and send a response including the plurality of content items to the client device in an order according to the determined priority scheme.
