A future goal is to have YSlow and PageSpeed beacon detailed information about a page's performance. This can be in addition to a normal GET request. The URL parameters can have basic information while a larger response in the POST body can contain detailed statistics regarding a page's assets and score. | A future goal is to have YSlow and PageSpeed beacon detailed information about a page's performance.

Starting with v2.0.1, besides the existing beacon preference: beaconUrl and optinBeacon, a new preference will be added to control the information to be included in the beacon. | |||
*Page load time | Preference Name: beaconInfo | ||
* | Possible values: "basic", "all", "grade", "stats", "comps" or a comma separated list of "grade", "stats" and "comps". | ||
* | |||
* | Default value of the preference is basic. The YSlow beacon will be sent with HTTP GET. This is for backward compatibility. | ||
* | |||
* | For all other values, the beacon will be sent by HTTP POST. | ||
* | |||
New beacon parameters: | |||
* lt - Page load time (v2.0.1, basic) | |||
* g - json tree of the resultset (scores of all rules in the ruleset) (v 2.0.1, grade) | |||
* w_c - page weight with primed cache (v2.0.1, stats) | |||
* r_c - number of requests with primed cache (v2.0.1, stats) | |||
* stats - json tree of stats, e.g. <pre>{"doc": { "r": 1, "w": 36.1 }, "js": {"r": 3, "w": 29.0 }</pre> (v2.0.1, stats) | |||
* stats_c - json tree of stats with primed cache (v2.0.1, stats) | |||
* comps - json tree of comps, e.g. <pre>{"doc": { "url": url, "w": size, "gzip": 36.1, "cr": 320, "cs": 971,"expires": "2009/10/11", "response": 537, "etag": "xxx-xx"}}</pre> (v2.0.1, comps) | |||
