## プロジェクトの歴史と使われ方

Forbidden is a security testing CLI for attempting bypasses of 4xx HTTP response status codes and related web access-control behaviors. Its README describes separate forbidden and stresser commands and states that the tool is based on Python Requests, PycURL, and Python's HTTP client.

### プロジェクトの歴史

The public project history available from official sources is mostly README-level rather than narrative. The maintained README documents a mature command set, a v13.4 build artifact in source-install instructions, and a roadmap of future tests such as hop-by-hop headers, User-Agent headers, cookies, HTTP smuggling, CRLF, Log4j, and AWS metadata SSRF.

### 採用の歴史

The README positions pip as the standard installation route and mentions a Homebrew formula as an alternative that is not maintained by the author. That combination places Forbidden in the common pentesting-tool distribution pattern of upstream Python packaging plus downstream CLI formulas.

### 使われ方

Typical use is to supply a target URL and choose test groups such as protocols, methods, uploads, overrides, headers, path mutations, encodings, authentication bypasses, redirects, and parser tests. The README cautions about proxies normalizing URLs, rate limiting, anti-bot protections, and engine-specific behavior.

### パッケージ好きにとっての重要性

Forbidden is package-nerd relevant as a compact example of a Python security CLI that depends on multiple HTTP engines to exercise edge cases that ordinary curl invocations cannot always produce, such as duplicate Host headers or requests without a Host header.

### タイムライン

- v13.4: README source-install instructions reference building forbidden-13.4-py3-none-any.whl.
- Current README: Homebrew installation is documented as an alternative not maintained by the author.

### Related projects

- The README names Python Requests, PycURL, and Python HTTP Client as implementation engines and links to internal forbidden.py, test.py, and value.py files for the test definitions.
