rewriteRequestURI

protected void rewriteRequestURI(RequestWrapper request,
                                 HttpRoute route)
                          throws ProtocolException

Deprecated.

Throws:

ProtocolException

execute

public HttpResponse execute(HttpHost targetHost,
                            HttpRequest request,
                            HttpContext context)
                     throws HttpException,
                            java.io.IOException

Deprecated.

Description copied from interface: RequestDirector

Executes a request.
Note: For the time being, a new director is instantiated for each request. This is the same behavior as for HttpMethodDirector in HttpClient 3.

Specified by:

execute in interface RequestDirector

Parameters:

targetHost - 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 for executing the request

Returns:

the final response to the request. This is never an intermediate response with status code 1xx.

Throws:

HttpException - in case of a problem

java.io.IOException - in case of an IO problem or if the connection was aborted

releaseConnection

protected void releaseConnection()

Deprecated.

Returns the connection back to the connection manager and prepares for retrieving a new connection during the next request.

determineRoute

protected HttpRoute determineRoute(HttpHost targetHost,
                                   HttpRequest request,
                                   HttpContext context)
                            throws HttpException

Deprecated.

Determines the route for a request. Called by execute(cz.msebera.android.httpclient.HttpHost, cz.msebera.android.httpclient.HttpRequest, cz.msebera.android.httpclient.protocol.HttpContext) to determine the route for either the original or a followup request.

Parameters:

targetHost - 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 execution, never null

Returns:

the route the request should take

Throws:

HttpException - in case of a problem

establishRoute

protected void establishRoute(HttpRoute route,
                              HttpContext context)
                       throws HttpException,
                              java.io.IOException

Deprecated.

Establishes the target route.

Parameters:

route - the route to establish

context - the context for the request execution

Throws:

HttpException - in case of a problem

java.io.IOException - in case of an IO problem

createTunnelToTarget

protected boolean createTunnelToTarget(HttpRoute route,
                                       HttpContext context)
                                throws HttpException,
                                       java.io.IOException

Deprecated.

Creates a tunnel to the target server. The connection must be established to the (last) proxy. A CONNECT request for tunnelling through the proxy will be created and sent, the response received and checked. This method does not update the connection with information about the tunnel, that is left to the caller.

Parameters:

route - the route to establish

context - the context for request execution

Returns:

true if the tunnelled route is secure, false otherwise. The implementation here always returns false, but derived classes may override.

Throws:

HttpException - in case of a problem

java.io.IOException - in case of an IO problem

createTunnelToProxy

protected boolean createTunnelToProxy(HttpRoute route,
                                      int hop,
                                      HttpContext context)
                               throws HttpException,
                                      java.io.IOException

Deprecated.

Creates a tunnel to an intermediate proxy. This method is not implemented in this class. It just throws an exception here.

Parameters:

route - the route to establish

hop - the hop in the route to establish now. route.getHopTarget(hop) will return the proxy to tunnel to.

context - the context for request execution

Returns:

true if the partially tunnelled connection is secure, false otherwise.

Throws:

HttpException - in case of a problem

java.io.IOException - in case of an IO problem

createConnectRequest

protected HttpRequest createConnectRequest(HttpRoute route,
                                           HttpContext context)

Deprecated.

Creates the CONNECT request for tunnelling. Called by createTunnelToTarget.

Parameters:

route - the route to establish

context - the context for request execution

Returns:

the CONNECT request for tunnelling

handleResponse

protected RoutedRequest handleResponse(RoutedRequest roureq,
                                       HttpResponse response,
                                       HttpContext context)
                                throws HttpException,
                                       java.io.IOException

Deprecated.

Analyzes a response to check need for a followup.

Parameters:

roureq - the request and route.

response - the response to analayze

context - the context used for the current request execution

Returns:

the followup request and route if there is a followup, or null if the response should be returned as is

Throws:

HttpException - in case of a problem

java.io.IOException - in case of an IO problem
