This node can be used to issue HTTP PUT requests. PUT requests are commonly used to create or replace remote resources.
The node allows you to either send a request to a fixed URL (which is specified in the dialog) or to a list of URLs provided by an optional input table. Every URL will result in one request which in turn will result in one row in the output table. You can define custom request headers in the dialog.
By default the output table will contain a column with the received data, its content type, and the HTTP
status code. The node tries to automatically convert the received data into a KNIME data type based on its
content type. In case no automatic conversion is possible, binary cells will be created.
You can extract additional response headers into column by defining them in the dialog.
The node supports several authentication methods, e.g. BASIC and DIGEST. Other authentication methods may be provided by additional extensions.
