Class DefaultConnectionReuseStrategyHC4

java.lang.Object
  org.apache.http.impl.DefaultConnectionReuseStrategyHC4

All Implemented Interfaces:

org.apache.http.ConnectionReuseStrategy

@Immutable
public class DefaultConnectionReuseStrategyHC4
extends java.lang.Object
implements org.apache.http.ConnectionReuseStrategy

Default implementation of a strategy deciding about connection re-use. The default implementation first checks some basics, for example whether the connection is still open or whether the end of the request entity can be determined without closing the connection. If these checks pass, the tokens in the Connection header will be examined. In the absence of a Connection header, the non-standard but commonly used Proxy-Connection header takes it's role. A token close indicates that the connection cannot be reused. If there is no such token, a token keep-alive indicates that the connection should be re-used. If neither token is found, or if there are no Connection headers, the default policy for the HTTP version is applied. Since HTTP/1.1, connections are re-used by default. Up until HTTP/1.0, connections are not re-used by default.

Since:

4.0

keepAlive in interface org.apache.http.ConnectionReuseStrategy

createTokenIterator

protected org.apache.http.TokenIterator createTokenIterator(org.apache.http.HeaderIterator hit)

Creates a token iterator from a header iterator. This method can be overridden to replace the implementation of the token iterator.

Parameters:

hit - the header iterator

Returns:

the token iterator
