/*
Package fasthttp provides fast HTTP server and client API.

Fasthttp provides the following features:

 1. Optimized for speed. Easily handles more than 100K qps and more than 1M
    concurrent keep-alive connections on modern hardware.

 2. Optimized for low memory usage.

 3. Easy 'Connection: Upgrade' support via RequestCtx.Hijack.

 4. Server provides the following anti-DoS limits:

    - The number of concurrent connections.

    - The number of concurrent connections per client IP.

    - The number of requests per connection.

    - Request read timeout.

    - Response write timeout.

    - Maximum request header size.

    - Maximum request body size.

    - Maximum request execution time.

    - Maximum keep-alive connection lifetime.

    - Early filtering out non-GET requests.

 5. A lot of additional useful info is exposed to request handler:

    - Server and client address.

    - Per-request logger.

    - Unique request id.

    - Request start time.

    - Connection start time.

    - Request sequence number for the current connection.

 6. Client supports automatic retry on idempotent requests' failure. Client
    response bodies are buffered by default; set Client.MaxResponseBodySize
    when requesting untrusted servers, since a non-positive value disables the
    limit.

 7. Fasthttp API is designed with the ability to extend existing client
    and server implementations or to write custom client and server
    implementations from scratch.
