Searchable Netlify redirects cheatsheet for the rules you actually write:
the `_redirects` file format, `netlify.toml` [[redirects]] blocks, 301 vs
302 vs 200 rewrites, the force `!` flag and shadowing, splats and `:splat`,
named placeholders, SPA fallbacks (`/* /index.html 200`), API proxying to
avoid CORS, query-parameter matching, country / language / role
conditions, custom 404 and 410 rules, and the debugging paths for "my
rule is not firing". The tool is fully local: search the reference,
filter by section, paste a `_redirects` file or a netlify.toml snippet to
parse each rule and catch known mistakes — catch-all rules that shadow
everything below them, `:splat` without a `*`, placeholders that never
match, invalid status codes, and self-redirect loops — then copy the
exact rule you need.
