Twelve HTTP status codes, by the book

For each HTTP status code below, report what the current HTTP Semantics specification says about it: its reason phrase, the section of that specification that defines it, and whether a response with that status code is heuristically cacheable (reusable by a cache without explicit freshness information). - 203 - 206 - 303 - 307 - 308 - 405 - 410 - 413 - 414 - 421 - 422 - 501 Research this with the provided web tools. Report, for every status code: - reason: the reason phrase exactly as the current specification gives it - section: the number of the section of the current specification that defines the code (just the number, e.g. "12.3.4") - heuristicallyCacheable: true if the specification defines responses with this code as heuristically cacheable, otherwise false - quote: a sentence from the numbered section of the specification that defines that status code (its own section, not an overview list or the table of contents), copied word for word (at least six words). - url: the URL of the page the quote comes from, which you opened with fetch_page. Write whatever explanation you like, then end the answer with one fenced JSON block of exactly this shape, with one entry per status code: ```json {"answers":[{"code":"203","reason":"…","section":"…","heuristicallyCacheable":true,"quote":"<a sentence copied word for word>","url":"<the URL of that page, as you opened it>"}]} ``` Quotes are checked against the text of the page at their URL, so copy them exactly. The block must be valid JSON: write a double quote inside a string as \".

Research rules: - The `search` and `fetch_page` tools are your only access to the web. Any other browsing tool is unavailable. - Search snippets are previews, not sources. Open a page with `fetch_page` before relying on what it says. - Long pages arrive one window at a time. Continue with `offset`, or use `find` to jump to a phrase. - Cite the URL of every source you rely on, next to the claim it supports. - Never cite a URL you did not open with `fetch_page`. A citation to an unopened page is scored as a fabrication. - Quotes must be copied word for word from the page you cite; they are checked against the page text. - Quote only passages the tools have shown you in this session. A quote recalled from memory does not count, even when the page contains it. - When sources disagree, say so explicitly and attribute each position, instead of silently picking one.
