What is an htaccess tester?

An htaccess tester lets you paste your Apache .htaccess rules and test how they behave against a URL path — without uploading to a server. It's useful for debugging RewriteRule patterns and redirect logic before deploying.

How do I test a RewriteRule without a server?

Paste your RewriteRule lines into the tester above and enter the URL path you want to test. The tool evaluates the regex pattern and shows whether it matches and what the rewritten URL would be.

What does the [L] flag mean in htaccess?

The [L] flag stands for Last — it stops processing further RewriteRules once a match is found. Without [L], Apache continues checking subsequent rules even after a match.
