Umlaut has a few custom URL parameters (can also be sent in a POST request) to control Umlaut behavior. All start with the prefix "umlaut.". These are generally added onto an OpenURL GET request.

umlaut.request_id

Specify an already created OpenURL request to act upon. Without this, Umlaut will still try to connect to an already created request *within the same session* based on a cache of OpenURLs seen in that session. But this process is not perfect. With umlaut.request_id, you can assure you are operating on the same request, and even if the client does not have cookies or a session.

umlaut.referent_id

Specify an Umlaut Referent object to re-use. Umlaut referent object represents a particular citation. Unlike umlaut.request_id, won't re-use an entire request (with responses and state), but only the specified citation.

umlaut.skip_resolve_menu

Set to "false" to override umlaut's configuration for conditionally skipping the the resolve menu and going straight to content. umlaut.skip_resolve_menu=false forces display of full resolve menu.

umlaut.skip_resolve_menu_for_type

Set to the name(s) of Umlaut service types (comma delimited), to force menu skipping (direct linking) for the first response found from any of the service types named.

umlaut.link_with_frameset

Set to "false" to force direct linking *without* the banner/frameset, just direct to vendor url.

umlaut.response_format

Generally used for API requests, value can be "xml", "json", or "jsonp". In case of jsonp, umlaut.jsonp=jsFunctionName can be used to determine the js function name that will be generated with the jsonp output
