Package org.apache.hc.core5.http Description

Core HTTP transport component APIs.

These deal with the fundamental things required for using the HTTP protocol, such as representing a message including it's headers and optional entity, and connections over which messages are sent. In order to prepare messages before sending or after receiving, there are interceptors for requests and responses.
