# HttpClientBase<!-- -->

Shared configuration and utilities for HTTP clients.

Provides common functionality for both sync and async HTTP clients including: header construction, parameter parsing, request body preparation, URL building, and timeout calculation.

Subclasses should call `super().__init__()` to initialize shared configuration. The helper methods are then available for use in the `call()` implementation.
