All Implemented Interfaces:

Serializable, Cloneable, HttpParams

public class HttpClientParams
extends HttpMethodParams

This class represents a collection of HTTP protocol parameters applicable to instances of HttpClient. Protocol parameters may be linked together to form a hierarchy. If a particular parameter value has not been explicitly defined in the collection itself, its value will be drawn from the parent collection of parameters.

Field Detail

CONNECTION_MANAGER_TIMEOUT

public static final String CONNECTION_MANAGER_TIMEOUT

Sets the timeout in milliseconds used when retrieving an HTTP connection from the HTTP connection manager.

This parameter expects a value of type Long.

See Also:

Constant Field Values

CONNECTION_MANAGER_CLASS

public static final String CONNECTION_MANAGER_CLASS

Defines the default HTTP connection manager class.

This parameter expects a value of type Class.

See Also:

Constant Field Values

PREEMPTIVE_AUTHENTICATION

public static final String PREEMPTIVE_AUTHENTICATION

Defines whether authentication should be attempted preemptively.

This parameter expects a value of type Boolean.

See Also:

Constant Field Values

REJECT_RELATIVE_REDIRECT

public static final String REJECT_RELATIVE_REDIRECT

Defines whether relative redirects should be rejected.

This parameter expects a value of type Boolean.

See Also:

Constant Field Values

MAX_REDIRECTS

public static final String MAX_REDIRECTS

Defines the maximum number of redirects to be followed. The limit on number of redirects is intended to prevent infinite loops.

This parameter expects a value of type Integer.

See Also:

Constant Field Values

ALLOW_CIRCULAR_REDIRECTS

public static final String ALLOW_CIRCULAR_REDIRECTS

Defines whether circular redirects (redirects to the same location) should be allowed. The HTTP spec is not sufficiently clear whether circular redirects are permitted, therefore optionally they can be enabled

This parameter expects a value of type Boolean.

Constant Field Values

Constructor Detail

HttpClientParams

public HttpClientParams()

Creates a new collection of parameters with the collection returned by DefaultHttpParams.getDefaultParams() as a parent. The collection will defer to its parent for a default value if a particular parameter is not explicitly set in the collection itself.

See Also:

DefaultHttpParams.getDefaultParams()

HttpClientParams

public HttpClientParams(HttpParams defaults)

Creates a new collection of parameters with the given parent. The collection will defer to its parent for a default value if a particular parameter is not explicitly set in the collection itself.

Parameters:

defaults - the parent collection to defer to, if a parameter is not explictly set in the collection itself.

See Also:

DefaultHttpParams.getDefaultParams()

Method Detail

getConnectionManagerTimeout

public long getConnectionManagerTimeout()

Returns the timeout in milliseconds used when retrieving an HTTP connection from the HTTP connection manager.

Returns:

timeout in milliseconds.

setConnectionManagerTimeout

public void setConnectionManagerTimeout(long timeout)

Sets the timeout in milliseconds used when retrieving an HTTP connection from the HTTP connection manager.

Parameters:

timeout - the timeout in milliseconds

getConnectionManagerClass

public Class getConnectionManagerClass()

Returns the default HTTP connection manager class.

Returns:

HTTP connection manager factory class.

setConnectionManagerClass

public void setConnectionManagerClass(Class clazz)

Sets HTTP connection manager class to be used der default.

Parameters:

clazz - HTTP connection manager factory class.

isAuthenticationPreemptive

public boolean isAuthenticationPreemptive()

Returns true if authentication should be attempted preemptively, false otherwise.

Returns:

true if authentication should be attempted preemptively, false otherwise.

setAuthenticationPreemptive

public void setAuthenticationPreemptive(boolean value)

Sets whether authentication should be attempted preemptively.

Parameters:

value - true if authentication should be attempted preemptively, false otherwise.

makeStrict

public void makeStrict()

Description copied from class: HttpMethodParams

Makes the HTTP methods strictly follow the HTTP protocol specification (RFC 2616 and other relevant RFCs). It must be noted that popular HTTP agents have different degree of HTTP protocol compliance and some HTTP serves are programmed to expect the behaviour that does not strictly adhere to the HTTP specification.

Overrides:

makeStrict in class HttpMethodParams

makeLenient

public void makeLenient()

Description copied from class: HttpMethodParams

Makes the HTTP methods attempt to mimic the exact behaviour of commonly used HTTP agents, which many HTTP servers expect, even though such behaviour may violate the HTTP protocol specification (RFC 2616 and other relevant RFCs).

Overrides:

makeLenient in class HttpMethodParams
