Frequently Asked Questions
Is my Apache configuration sent to a server?
No. All validation is performed entirely in your browser using JavaScript. Your configuration data never leaves your device.
What does this validator check?
It checks for balanced opening/closing tags, validates common Apache directives, inspects IfModule blocks for proper syntax, checks RewriteRule syntax, and reviews SSL configuration patterns. It is a best-effort syntax validator and may not catch every possible runtime error.
Can I validate .htaccess files with this tool?
Yes. The validator works with both httpd.conf-style configurations and .htaccess files. Simply paste your .htaccess content into the input area and click Validate.
Why does my valid configuration show warnings?
Warnings indicate potential issues that are not strictly syntax errors, such as uncommon directive usage or missing recommended SSL settings. Review warnings carefully, but they may be acceptable depending on your setup.
Does this tool support all Apache directives?
It covers a broad set of commonly used Apache directives, but it does not include every directive from every Apache module. If a directive is not recognized, it will flag it as unknown rather than fail validation.
