Examples of org.openqa.jetty.http.HttpFields

org.openqa.jetty.http.HttpFields
HTTP Fields. A collection of HTTP header and or Trailer fields. This class is not synchronized and needs to be protected from concurrent access. This class is not synchronized as it is expected that modifications will only be performed by a single thread. @version $Id: HttpFields.java,v 1.77 2006/11/22 20:02:15 gregwilkins Exp $ @author Greg Wilkins (gregw)
