How to Generate an Apache .htaccess File with Redirect and Cache Rules

Choose the redirect, cache, security-header, and custom-rule options you need, then generate Apache .htaccess configuration text for review. Supplied values remain your responsibility to inspect before separate use.

Purpose of the configuration generator

The .htaccess Generator creates Apache configuration text for a site’s .htaccess file. You can start with the default configuration or add selected rewrite rules, cache-expiration directives, security-header directives, and custom rules. This is useful when you want to assemble a configuration draft from a few deliberate choices rather than type every section yourself.

The generated material is text for inspection in the context of your Apache setup. It does not, by itself, change the configuration of a server. Treat each selected option and each supplied value as part of a draft that needs a technical review before it enters your separate deployment process.

Procedure for choosing and checking options

1. Open the generator and examine the available controls before choosing options. If you keep the defaults, the result contains generated configuration text without redirect, cache, security-header, or custom-rule sections.

2. Choose a redirect mode. The choices are none, HTTPS, WWW, and custom. HTTPS creates a 301 rewrite configuration for requests whose HTTPS status is off; it sends those requests to the same host over HTTPS and preserves the captured path. WWW creates a case-insensitive 301 rewrite rule that redirects the captured path to the www version of the host over HTTPS. Custom adds a 301 rule only when you select that mode and provide a non-empty redirect URL, with the captured path preserved.

3. Select a cache-control value if the draft should contain an Apache expiration block. A value other than none is placed in the access-plus expiration text. Check that the value matches the syntax and behavior you intend to review, because the generator does not validate or escape it.

4. Turn on the security-header option when you want the output to contain directives for nosniff content-type protection, denying framing, and XSS protection. Read these as the specific directives included by this option, not as a claim that the resulting configuration covers every security requirement.

5. Add custom rules only after preparing text that you can inspect line by line. When the input contains more than whitespace, the generator appends it after a custom-rules marker in its original form. The supplied rules are not transformed, validated, escaped, or executed by the generator.

6. Generate the configuration and read the complete output from top to bottom. Compare the rewrite portion with the selected redirect mode, look for the expiration block when a non-default cache value was chosen, and locate the security-header and custom-rule sections when enabled or supplied. Review redirects, cache text, headers, and custom rules against the Apache environment where you plan to use them.

Reading the generated text

With default inputs, the output has generated configuration text but no optional redirect, cache, security-header, or custom-rule section. Selecting HTTPS changes the rewrite portion to handle requests without HTTPS, whereas WWW uses the described host condition and HTTPS destination. The custom mode depends on a non-empty redirect URL, so selecting the mode alone does not add that rule.

A cache choice other than none indicates that an expiration block should appear in the generated text. Enabling the header option produces the three described protection directives, and non-whitespace custom input appears after the custom-rules marker in the form supplied. These visible sections let you compare the result with the choices made in the form.

The generator’s role is to produce Apache .htaccess configuration text. Its handling of supplied redirect URLs, cache values, and custom rules is insertion into the generated directives rather than validation or escaping, so the output should be assessed for the intended Apache context before it is used.

Worked example

A site owner prepares configuration text that combines an HTTPS redirect with the available security-header directives for review in a separate Apache workflow.

For a site that needs HTTP requests redirected to HTTPS, select HTTPS mode, enable the security-header option, leave cache control at none, leave custom rules blank, and generate the configuration.

The generated text has an HTTPS rewrite section and directives for nosniff content-type protection, denying framing, and XSS protection, with no cache or custom-rule section from the stated choices.

Limitations

• Redirect URLs, cache values, and custom rules are inserted into the generated directives without validation or escaping, so the text requires review for its intended Apache context.

Common errors

• A redirect URL or custom rule may be unsuitable when it is entered with the assumption that the generator will check it. Inspect the supplied text and confirm its intended Apache syntax before using the generated configuration.

FAQ

Does the generator apply the configuration to Apache?

The generator creates Apache .htaccess configuration text; applying that text to a server is outside the generation described here.

What does HTTPS mode put in the output?

HTTPS mode adds a 301 rewrite configuration for requests with HTTPS turned off, sending them to the same host over HTTPS while preserving the captured path.

What condition adds a custom redirect rule?

The custom rule appears when custom redirect mode is selected and the redirect URL is non-empty; that value is inserted without validation or escaping.
