Class HttpConfiguration

  • All Implemented Interfaces:
    Dumpable
    @ManagedObject("HTTP Configuration")
public class HttpConfiguration
extends java.lang.Object
implements Dumpable
    HTTP Configuration.

    This class is a holder of HTTP configuration for use by the HttpChannel class. Typically an HTTPConfiguration instance is instantiated and passed to a HttpConfiguration.ConnectionFactory that can create HTTP channels (e.g. HTTP, AJP or FCGI).

    The configuration held by this class is not for the wire protocol, but for the interpretation and handling of HTTP requests that could be transported by a variety of protocols.

        The max idle time is applied to an HTTP request for IO operations and delayed dispatch.

        Returns:
        the max idle time in ms or if == 0 implies an infinite timeout, <0 implies no HTTP channel timeout and the connection timeout is used instead.

      • setIdleTimeout

        public void setIdleTimeout​(long timeoutMs)

        The max idle time is applied to an HTTP request for IO operations and delayed dispatch.

        Parameters:
        timeoutMs - the max idle time in ms or if == 0 implies an infinite timeout, <0 implies no HTTP channel timeout and the connection timeout is used instead.

      • getBlockingTimeout

@Deprecated
public long getBlockingTimeout()
        Deprecated.
        Replaced by getMinResponseDataRate() and getMinRequestDataRate()

        This timeout is in addition to the Connector.getIdleTimeout(), and applies to the total operation (as opposed to the idle timeout that applies to the time no data is being sent). This applies only to blocking operations and does not affect asynchronous read and write.

        Returns:
        -1, for no blocking timeout (default), 0 for a blocking timeout equal to the idle timeout; >0 for a timeout in ms applied to the total blocking operation.

        This timeout is in addition to the Connector.getIdleTimeout(), and applies to the total operation (as opposed to the idle timeout that applies to the time no data is being sent).This applies only to blocking operations and does not affect asynchronous read and write.

        Parameters:
        blockingTimeout - -1, for no blocking timeout (default), 0 for a blocking timeout equal to the idle timeout; >0 for a timeout in ms applied to the total blocking operation.

      • setOutputBufferSize

        public void setOutputBufferSize​(int outputBufferSize)
        Set the size of the buffer into which response content is aggregated before being sent to the client. A larger buffer can improve performance by allowing a content producer to run without blocking, however larger buffers consume more memory and may induce some latency before a client starts processing the content.

        outputBufferSize - buffer size in bytes.

      • setOutputAggregationSize

        public void setOutputAggregationSize​(int outputAggregationSize)
        Set the max size of the response content write that is copied into the aggregate buffer. Writes that are smaller of this size are copied into the aggregate buffer, while writes that are larger of this size will cause the aggregate buffer to be flushed and the write to be executed without being copied.
        Parameters:
        outputAggregationSize - the max write size that is aggregated

      • setRequestHeaderSize

        Parameters:
        requestHeaderSize - the maximum size in bytes of the request header

      • setResponseHeaderSize

        public void setResponseHeaderSize​(int responseHeaderSize)

        Parameters:
        responseHeaderSize - the maximum size in bytes of the response header

      • setHeaderCacheSize
