request.getHeaders()
public java.util.Enumeration getHeaders(java.lang.String name)Returns all the values of the specified request header as an Enumeration of String objects. Some headers, such as Accept-Language can be sent by clients as several headers each with a different value rather than sending the header as a comma separated list. If the request did not include any headers of the specified name, this method returns an empty Enumeration. The header name is case insensitive. You can use this method with any request header. Parameters:name - a String specifying the header name Returns:an Enumeration containing the values of the requested header. If the request does not have any headers of that name return an empty enumeration. If the container does not allow access to header information, return null
