The HTTP client Connector can be used in four different
AssemblyLine modes provided here.
- Iterator
- Each call to the Connector requests the same URL configured for
the Connector. This causes the Connector to run forever requesting
the same page unless you include a Parser in the Connector's configuration.
If you include a Parser, the Parser notifies when the last entry has
been read from the connection and the Connector eventually causes
an AssemblyLine to stop.
- Lookup
- In this mode the Connector requests a page every time the Lookup
function is called. In your search criteria you can specify the page
or URL to request, or include any number of parameters all of which
are appended to the base URL as request parameters.
- AddOnly
- In this mode the Connector request is performed much like the
Iterator mode.
- Call/Reply
- In this mode the Connector has two attribute maps, Input and Output.
When the AssemblyLine invokes the Connector, an Output map operation
is performed, followed by an Input map operation.
