#### A.10.1.13 View URL

Configuration for View URL action

The View URL activation type uses a URL column and a column giving the MIME type from the activated row, and tries to display the resource in a suitable way for content of the indicated type.

Configuration:

Resource URL
  Identifies a column giving the URL of the remote resource to display.
MIME Type
  Identifies a column in the table giving the MIME type (Content Type) of the resource at the URL. Different types of resource will be displayed by default in different ways.
Auto Invoke
  If set true (checked) the URL will be displayed without further user intervention. By default, this tries to do something sensible according to the MIME type; if it's a DataLink table it displays it in a DataLink window, if it's another VOTable it loads it into TOPCAT, if it's a PNG it displays it in an image window, etc. If set false, then a View URL window will be popped up which lets you configure the action required per resource type, and invoke it manually using an Invoke button. This window is like the panel at the bottom of the Datalink Window. If you can configure it to your satisfaction, you can set the Auto Invoke setting back to false and future activations will proceed without the View URL window popping up again.
