Behavior
This page converts a url into a dialog action request. A faster, but less general, form of this facility is provided by dialog action do.

Two url query parameter names are reserved; all other url query parameters are converted into dialog parameters. Required url query parameter  names the action to be requested. Optional url query parameter  if present causes the page to request confirmation from the user before sending the action request. If parameter  is present, the action request is authenticated; if parameter   is not present, the action request is not authenticated.

As presently implemented, this is a slow operation. Use of a dialog button already incurs a substantial time delay while loading the target-action page; following a link to this page incurs double the delay, first loading page Dialog and then loading the target-action page.
