Htaccess Generator

Create a narrow Apache 2.4 .htaccess for fixed-host HTTPS canonicalization, optional directory-listing disablement and a local custom 404 path.

Privacy: your files never leave your device. All processing happens locally in your browser.

How to use

  1. 1.Enter the exact canonical origin and select only the directory-listing and local 404 options your Apache host permits.
  2. 2.Review the fixed-host rules, back up the existing .htaccess and merge carefully with CMS or authentication directives.
  3. 3.Deploy on staging, validate Apache configuration and test HTTP, HTTPS, alternate-host and missing-page requests before production.

About Htaccess Generator

Htaccess Generator creates a deliberately narrow Apache 2.4 configuration for three common document-root tasks: redirecting to one fixed HTTPS hostname, disabling automatic directory listings and selecting a local custom 404 document. It does not attempt to synthesize an entire server configuration.

Enter the exact canonical site origin, such as https://www.example.com. The input must contain only a public domain origin: no credentials, port, path, query or fragment. The generator always builds an HTTPS target and escapes hostname dots in the RewriteCond regular expression.

The redirect block enables mod_rewrite, checks whether Apache sees the request as non-HTTPS or the Host header differs from the fixed canonical domain, and issues one 301 redirect to the fixed host while preserving REQUEST_URI. Using a fixed destination avoids constructing an external redirect from an untrusted Host value.

A permanent redirect tells browsers and search engines that the canonical location should replace the old one. Test with temporary or staging infrastructure before production because cached 301 responses can persist. Confirm both HTTP and alternate-host requests reach the intended path and query on the canonical HTTPS site.

The HTTPS condition reads Apache's mod_ssl state. It is not appropriate unchanged when TLS terminates at a reverse proxy or load balancer and Apache receives plain HTTP. In that architecture the condition can loop. Adapt the rule to a trusted, overwritten proxy header only when you control the proxy path and understand spoofing risks.

The optional Options -Indexes line asks Apache not to generate a directory listing when no index resource is present. It requires the server to permit the Options directive in .htaccess. If AllowOverride does not include the needed category, Apache may return a 500 error instead of applying the file.

The optional ErrorDocument rule accepts one local URL path beginning with slash. It rejects external URLs, whitespace, queries and fragments. A local path keeps the error response within the site, but that target must exist and must not itself trigger an error loop. Apache requires the relevant FileInfo override permission.

The generated file assumes it is placed in the website document root and that mod_rewrite is available. Per-directory rewrite context behaves differently from virtual-host configuration. If you control the main Apache configuration, official documentation often recommends simpler virtual-host Redirect directives for canonical HTTP-to-HTTPS handling.

Back up the existing .htaccess before replacing anything. Existing CMS front-controller rules, authentication, cache headers, compression or access restrictions may depend on ordering. Merge only after understanding those rules; blindly replacing the whole file can take a site offline or bypass intended routing.

The tool does not connect to a server, detect Apache, inspect enabled modules, read AllowOverride, validate certificate coverage or run apachectl -t. A syntactically plausible file can still be incompatible with hosting policy. Production correctness requires server-side configuration validation and real HTTP checks.

Eight Apache-backed fixtures cover the HTTPS condition, literal hostname condition, fixed-host 301 target, normalization from an HTTP input, subdomain escaping, directory index disablement and two local 404 paths. Boundary tests reject credentials, IP addresses, non-origin URLs and external error targets.

Use the generator by entering the final hostname, selecting only directives your hosting environment permits and reviewing the output. Save the current server file, deploy first to staging or a reversible maintenance window, validate Apache configuration, and request representative HTTP, HTTPS, canonical-host, alternate-host and missing-page URLs.

If any request loops or returns 500, restore the backup immediately. Check error logs for disallowed directives or missing modules. This focused generator reduces the rule surface, but server configuration remains operationally sensitive and must be verified where Apache actually runs.

Methodology & sources

A credential-free domain origin is normalized to a fixed HTTPS host, regex metacharacters are escaped for a negative HTTP_HOST condition, and mod_ssl plus host conditions feed one R=301,L RewriteRule. Optional local Options and ErrorDocument directives use strict inputs.
