1. A computer-implemented method of regulating server load, the method comprising:

  • monitoring a load level of a server system that provides network-based access to a retrievable content resource;

    regulating the load level of the server system by varying time-to-live (TTL) values sent to requester devices with the retrievable content resource, such that the TTL values are varied according to a function in which TTL values are directly proportional to the load level of the server system, whereby increases in the load level of the server system cause higher TTL values to be used; and

    adaptively varying an algorithm used to calculate said TTL values based on load regulation feedback data reflective of an effectiveness of the TTL values;

    said method performed programmatically by a computing system.
