Class LowLevelHttpRequest (1.42.3) 

public abstract class LowLevelHttpRequest

Low-level HTTP request.

This allows providing a different implementation of the HTTP request that is more compatible with the Java environment used.

Implementation has no fields and therefore thread-safe, but sub-classes are not necessarily thread-safe.
