DATASINK attribute
The DATASINK attribute allows a WebXpresso plugin instance to
indicate a cgi program to receive the user input that occurred in
controls in the plugin drawing. The cgi receives a query string that
includes the name, type, and values from the control with which
the user interacted.
The query string is of the form <name1>=<value1>&<name2>=<value2>&....
The possible names are:
- Origin: The hierarchial resource string indicating the input object.
- Value1: The value of an input object that produces a float value.
- Value2: The second value of an input object that produces two float values.
- Value3: The third value of an input object that produces three float values.
- String1: The value of an input object that produces a string value.
- String2: The second value of an input object that produces two string value.
