Example 1 of Complete EdgePeak Setup

In this example, we setup a server with Prometheus exporter enabled, and this server replies to /hi/john with Hello World ! and proxy and caches requests to /upstream/* to an upstream server. Caching in RAM is enabled by default.

config.prometheus_address = "127.0.0.1";
config.prometheus_port = 11450;

config.vhosts["vh1"] = {
      .endpoints = {endpoint(HTTP, 80), endpoint(HTTPS, 443)},
};

config.upstreams["origins"] = {
      .endpoints = {"http://127.0.0.1:8100"}
};

config.vhost["vh1"] << route(GET | HEAD, "/upstream/.*", [](
    client_request req, client_reply rpy) -> future<>{
      req.filter_args("minrate", "maxrate", "b"); // Filter query args to keep only those
      req.remove_header("Cookie"); // Do not forward cookie to upstream server
      co_await rpy.set_proxy(req, "origins");
});

config.vhosts["vh1"] << route(GET | HEAD, "/hi/.*", [](
    client_request& req, client_reply& rpy){
      rpy.set_header("X-Served-By", "HPC");
      co_await rpy.set_accept(req, "Hello World !");
});
