contextHandle	The contextHandle addresses a specific IFD.	Optional1

Content-Types

text/html

Webpage with user evaluatable content. E.g. error page, manual redirect, ...

Description
The interface can be used to start the eID application.

The parameters ifdName, contextHandle, slotHandle and cardType address a particular eCard, or a type of card.
There are three meaningful combinations of the optional parameters:

• none
  Use the fist nPa available. Display a "Please insert nPa" dialog if needed. This is the behaviour of the AusweisApp.
• cardType
  Use the fist card of the specified type which is available. Display a "Please insert <cardType>" dialog if needed.
• ifdName, contextHandle, slotHandle
  Use exactly the card matching the parameters.

Notes

TODO
* What happens if the Client Activator cannot start an application?
* What happens if the Client Activator cannot fetch a TC Token from the given TCTokenURL? Should that result in a 400 or 404?
