webd:parameter

Purpose

Defines an HTTP parameter. There are also element forms for some attribute values.

You can use the target attribute to preserve the origin of a parameter, which will by default be merged with other parameter values in a request according to the method used. A value of 'default' puts a parameter in the query string if the method is GET, and in the body if the method is POST. A value of 'query' explicitly adds it to the query string, and 'body' adds it to the body, regardless of method.

Note:

It is an error to specify 'body' on the target attribute inside the webd:get element.
