Apache HttpComponents – HttpClient Examples (Async) (original) (raw)

• Asynchronous HTTP exchange
  This example demonstrates a basic asynchronous HTTP request / response exchange. Response content is buffered in memory for simplicity.
• Asynchronous HTTP exchange with content streaming
  This example demonstrates an asynchronous HTTP request / response exchange with a full content streaming.
• Pipelined HTTP/1.1 exchanges
  This example demonstrates a pipelined execution of multiple HTTP/1.1 request / response exchanges. Response content is buffered in memory for simplicity.
• Multiplexed HTTP/2 exchanges
  This example demonstrates a multiplexed execution of multiple HTTP/2 request / response exchanges. Response content is buffered in memory for simplicity.
• Request execution interceptors
  This example demonstrates how to insert custom request interceptor and an execution interceptor to the request execution chain.
• Message trailers
  This example demonstrates how to use a custom execution interceptor to add trailers to all outgoing request enclosing an entity..
• Multiplexed HTTP/2 exchanges

This example demonstrates handling of HTTP/2 message exchanges pushed by the server.

• Client authentication
  This example demonstrates execution of an HTTP request against a target site that requires user authentication.
• Custom SSL context
  This example demonstrates how to create secure connections with a custom SSL context.
• Connection / TLS configuation per route / host
  This example demonstrates how to use connection configuration on a per-route or a per-host basis.
• Connection eviction
  This example demonstrates how to evict expired and idle connections from the connection pool.
• Preemptive BASIC authentication
  This example shows how HttpClient can be customized to authenticate preemptively using BASIC scheme. Generally, preemptive authentication can be considered less secure than a response to an authentication challenge and therefore discouraged.
• HTTP version negotiation
  This example demonstrates how to make HttpClient negotiate or force a particular version of HTTP protocol during the TLS handshake. Please note that protocol version policy setting also applies to non-HTTPS connections.
• Virtual HTTPS / SNI
  This example demonstrates how to use SNI to send requests to a virtual HTTPS endpoint using the async I/O.
