Generate .htaccess rules
Compose HTTPS, www, redirect and deny rules for Apache. Assembly runs locally — paste the result into your project's .htaccess.
RewriteEngine On
# Force HTTPS
RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
# Remove www.
RewriteCond %{HTTP_HOST} ^www\.example\.com$ [NC]
RewriteRule ^(.*)$ https://example.com/$1 [L,R=301]
# Custom redirects
Redirect 301 /old-page /new-page
Redirect 302 /another-old /another-new
# Deny access to sensitive files
<FilesMatch "\.git">
Require all denied
</FilesMatch>
<FilesMatch "\.env">
Require all denied
</FilesMatch>
# Disable directory listing
Options -IndexesHow to use .htaccess
Apache reads .htaccess on every request inside its containing directory. Keep rules minimal for performance.
- 01
Pick canonical host
Choose www or apex and force HTTPS — search engines pick one canonical.
Lookups reference the IANA registries (MIME, HTTP status, TLDs) bundled at build time — no live network calls, no rate limits, no leaked queries.

Add redirects
One per line: source target status. 301 for permanent, 302 for temporary.
Builders emit canonical syntax per the relevant RFC (9110 for HTTP, 5322 for headers, 3986 for URLs) so the output passes spec-compliant parsers.

Deploy
Save as .htaccess in your document root. Apache reloads automatically.
Copy writes the snippet directly into your clipboard; downloads emit the right extension and MIME so curl/httpie pick them up correctly.

Web-spec details that bite later
Idempotency saves retries
POST/PUT/DELETE should be safely retried. Use idempotency keys and return the same response on duplicate requests.
Match RFC 9110 status codes
Don’t invent codes. 422 for validation errors, 409 for conflicts, 429 for rate limits. Standard codes work with off-the-shelf clients.
Set <code>Cache-Control</code> deliberately
Default browser caching is conservative. Use max-age + stale-while-revalidate for hot endpoints.
Validate Open Graph in dev
OG tags break silently. Use a previewer like OG Generator + Facebook’s debugger before launch.
CORS is a server concern
The browser sends the preflight; the server decides. Wildcard origins disable credentials — be explicit.
MIME drives behaviour
Servers must send the right Content-Type. Browsers sniff but the spec says they shouldn’t — be explicit to avoid surprises.
When to write .htaccess
Shared hosting, legacy sites, quick redirects.
HTTPS enforcement
One rule redirects every HTTP request to TLS. Bundled from IANA registries at build time — no live network call, no rate limit, no leaked queries. The MIME, TLD, and status-code tables are baked in so the tool works offline once loaded.
spec-compliantCanonical host
Pick www vs apex once for SEO sanity. Output is canonical per the relevant RFC (9110 for HTTP, 5322 for headers, 3986 for URLs), so spec-compliant parsers accept it as-is. Cross-browser and cross-library behaviour stays consistent.
offlinePage renames
301 old URLs to preserve link equity. Pairs with the curl-to-fetch converter for end-to-end test stubs — copy the curl from DevTools, paste, get an idiomatic fetch() body. Drop into Playwright/Vitest fixtures without manual translation.
IANA-backedSensitive files
Hide .env, .git, .htpasswd from the public. Catches common pitfalls (uppercase header names, smart quotes inside Content-Type, missing ;charset=utf-8) before they bite production. Validation flags rather than auto-corrects so you stay in control.
RFC-alignedTrailing slash
Normalise slash policy for clean analytics. Validation runs as you type — copy only when the output is shaped correctly. The output drops directly into nginx, Apache, or CDN configs without re-formatting or re-quoting.
production-gradeShared hosting
.htaccess is the only config you can write on cPanel hosts. Same input plus same options always produces identical canonical output, so the tool is safe to embed in CI scripts that diff against expected configs.
