add method
Adds a header value. The header named name
will have the value value
added
to its list of values.
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) {
if (value is List) {
for (int i = 0; i < value.length; i++) {
_addValue(name, value[i]);
}
} else {
_addValue(name, value);
}
}
