Re: Beacon API

In the cases I see we are never interested in the response. The question
would also be how to handle it as the page that initiated it might - or
will - no longer be there.

I do not see how this relates to the ping. If I understand the Ping
correctly it send back the ping when a ling was clicked. The scenario here
is totally different. An analytics tool - whether RUM or other analytics -
collects a set of data like timing values etc. and then wants to beacon
this data back to the server for further processing. I am not sure how to
achieve this using the ping attribute.

This could be achieved by a method like this:

beacon (method, URL, postBody);

Today people are also using img tags that are dynamically created to
achieve this. This has the downside that a) it does not always work and b)
is limited in the amount of data that can be sent back due to URL length
