public abstract class LowLevelHttpRequest extends Object
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.

will be called for each instance of the header.
