org.apache.http.impl.conn.ProxySelectorRoutePlanner

All Implemented Interfaces:

HttpRoutePlanner

Deprecated.

(4.3) use SystemDefaultRoutePlanner

@Deprecated
public class ProxySelectorRoutePlanner
extends Object
implements HttpRoutePlanner

Default implementation of an HttpRoutePlanner. This implementation is based on ProxySelector. By default, it will pick up the proxy settings of the JVM, either from system properties or from the browser running the application. Additionally, it interprets some parameters, though not the DEFAULT_PROXY.

The following parameters can be used to customize the behavior of this class:

• ConnRoutePNames.LOCAL_ADDRESS
• ConnRoutePNames.FORCED_ROUTE

Since:

4.0

Constructor Detail

ProxySelectorRoutePlanner

public ProxySelectorRoutePlanner(SchemeRegistry schreg,
                         ProxySelector prosel)

Deprecated.

Creates a new proxy selector route planner.

Parameters:

schreg - the scheme registry

prosel - the proxy selector, or null for the system default

Method Detail

getProxySelector

public ProxySelector getProxySelector()

Deprecated.

Obtains the proxy selector to use.

Returns:

the proxy selector, or null for the system default

setProxySelector

public void setProxySelector(ProxySelector prosel)

Deprecated.

Sets the proxy selector to use.

Parameters:

prosel - the proxy selector, or null to use the system default

determineRoute

public HttpRoute determineRoute(HttpHost target,
                       HttpRequest request,
                       HttpContext context)
                         throws HttpException

Deprecated.

Description copied from interface: HttpRoutePlanner

Determines the route for a request.

Specified by:

determineRoute in interface HttpRoutePlanner

Parameters:

target - the target host for the request. Implementations may accept null if they can still determine a route, for example to a default target or by inspecting the request.

request - the request to execute

context - the context to use for the subsequent execution. Implementations may accept null.

Returns:

the route that the request should take

Throws:

HttpException - in case of a problem

determineProxy

protected HttpHost determineProxy(HttpHost target,
                      HttpRequest request,
                      HttpContext context)
                           throws HttpException

Deprecated.

Determines a proxy for the given target.

Parameters:

target - the planned target, never null

request - the request to be sent, never null

context - the context, or null

Returns:

the proxy to use, or null for a direct route

Throws:

HttpException - in case of system proxy settings that cannot be handled

getHost

protected String getHost(InetSocketAddress isa)

Deprecated.

Obtains a host from an InetSocketAddress.

Parameters:

isa - the socket address

Returns:

a host string, either as a symbolic name or as a literal IP address string

(TODO: determine format for IPv6 addresses, with or without [brackets])

chooseProxy

protected Proxy chooseProxy(List<Proxy> proxies,
                HttpHost target,
                HttpRequest request,
                HttpContext context)

Deprecated.

Chooses a proxy from a list of available proxies. The default implementation just picks the first non-SOCKS proxy from the list. If there are only SOCKS proxies, Proxy.NO_PROXY is returned. Derived classes may implement more advanced strategies, such as proxy rotation if there are multiple options.

Parameters:

proxies - the list of proxies to choose from, never null or empty

target - the planned target, never null

request - the request to be sent, never null

context - the context, or null

Returns:

a proxy type
