public class HttpHeaders extends Object implements MultiValueMap<String,String>, Serializable
In addition to the regular methods defined by Map
, this class offers many common
convenience methods, for example:
getFirst(String)
returns the first value associated with a given header nameadd(String, String)
adds a header value to the list of values for a header nameset(String, String)
sets the header value to a single string valueNote that HttpHeaders
generally treats header names in a case-insensitive manner.
