Class RequestConfig

  • All Implemented Interfaces:
    java.lang.Cloneable
    @Contract(threading=IMMUTABLE)
public class RequestConfig
extends java.lang.Object
implements java.lang.Cloneable
    Immutable class encapsulating request configuration items. The default setting for stale connection checking changed to false, and the feature was deprecated starting with version 4.4.

    • Method Detail

      • isExpectContinueEnabled

        public boolean isExpectContinueEnabled()
        Determines whether the 'Expect: 100-Continue' handshake is enabled for entity enclosing methods. The purpose of the 'Expect: 100-Continue' handshake is to allow a client that is sending a request message with a request body to determine if the origin server is willing to accept the request (based on the request headers) before the client sends the request body.

        The use of the 'Expect: 100-continue' handshake can result in a noticeable performance improvement for entity enclosing requests (such as POST and PUT) that require the target server's authentication.

        'Expect: 100-continue' handshake should be used with caution, as it may cause problems with HTTP servers and proxies that do not support HTTP/1.1 protocol.

        Default: false

      • getProxy

        public HttpHost getProxy()
        Returns HTTP proxy to be used for request execution.

        Default: null

      • getLocalAddress

        public java.net.InetAddress getLocalAddress()
        Returns local address to be used for request execution.

        On machines with multiple network interfaces, this parameter can be used to select the network interface from which the connection originates.

        Default: null

      • isStaleConnectionCheckEnabled

        @Deprecated
public boolean isStaleConnectionCheckEnabled()
        Deprecated.
        (4.4) Use PoolingHttpClientConnectionManager.getValidateAfterInactivity()
        Determines whether stale connection check is to be used. The stale connection check can cause up to 30 millisecond overhead per request and should be used only when appropriate. For performance critical operations this check should be disabled.

        Default: false since 4.4

      • getCookieSpec

        public java.lang.String getCookieSpec()
        Determines the name of the cookie specification to be used for HTTP state management.

        Default: null

      • isRedirectsEnabled

        public boolean isRedirectsEnabled()
        Determines whether redirects should be handled automatically.

        Default: true

      • isRelativeRedirectsAllowed

        public boolean isRelativeRedirectsAllowed()
        Determines whether relative redirects should be rejected. HTTP specification requires the location value be an absolute URI.

        Default: true

      • isCircularRedirectsAllowed

        public boolean isCircularRedirectsAllowed()
        Determines 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

        Default: false

      • getMaxRedirects

        public int getMaxRedirects()
        Returns the maximum number of redirects to be followed. The limit on number of redirects is intended to prevent infinite loops.

        Default: 50

      • isAuthenticationEnabled

        public boolean isAuthenticationEnabled()
        Determines whether authentication should be handled automatically.

        Default: true

      • getTargetPreferredAuthSchemes

        public java.util.Collection<java.lang.String> getTargetPreferredAuthSchemes()
        Determines the order of preference for supported authentication schemes when authenticating with the target host.

        Default: null

      • getProxyPreferredAuthSchemes

        public java.util.Collection<java.lang.String> getProxyPreferredAuthSchemes()
        Determines the order of preference for supported authentication schemes when authenticating with the proxy host.

        Default: null

      • getConnectionRequestTimeout

        public int getConnectionRequestTimeout()
        Returns the timeout in milliseconds used when requesting a connection from the connection manager.

        A timeout value of zero is interpreted as an infinite timeout. A negative value is interpreted as undefined (system default if applicable).

        Default: -1

      • getConnectTimeout

        public int getConnectTimeout()
        Determines the timeout in milliseconds until a connection is established.

        A timeout value of zero is interpreted as an infinite timeout. A negative value is interpreted as undefined (system default if applicable).

        Default: -1

      • getSocketTimeout

        public int getSocketTimeout()
        Defines the socket timeout (SO_TIMEOUT) in milliseconds, which is the timeout for waiting for data or, put differently, a maximum period inactivity between two consecutive data packets).

        A timeout value of zero is interpreted as an infinite timeout. A negative value is interpreted as undefined (system default if applicable).

        Default: -1

      • isDecompressionEnabled

        @Deprecated
public boolean isDecompressionEnabled()
        Deprecated.
        (4.5) Use isContentCompressionEnabled()
        Determines whether compressed entities should be decompressed automatically.

        Default: true

        Since:
        4.4

      • isContentCompressionEnabled

        public boolean isContentCompressionEnabled()
        Determines whether the target server is requested to compress content.

        Default: true

        Since:
        4.5

      • isNormalizeUri

        public boolean isNormalizeUri()
        Determines whether client should normalize URIs in requests or not.

        Default: true

        Since:
        4.5.8

      • toString

        public java.lang.String toString()
        Overrides:
        toString in class java.lang.Object
