# add method

void add (String name, Object value)

Adds a header value. The header named `name` will have the value `value` added to its list of values. Some headers are single valued, and for these adding a value will replace the previous value. If the value is of type DateTime a HTTP date format will be applied. If the value is a `List` each element of the list will be added separately. For all other types the default `toString` method will be used.

## Implementation

    void add(String name, Object value);
