Package org.eclipse.jetty.http

Class HttpGenerator

java.lang.Object

org.eclipse.jetty.http.HttpGenerator

public class HttpGenerator
extends Object

HttpGenerator. Builds HTTP Messages.

If the system property "org.eclipse.jetty.http.HttpGenerator.STRICT" is set to true, then the generator will strictly pass on the exact strings received from methods and header fields. Otherwise a fast case insensitive string lookup is used that may alter the case and white space of some methods/headers
