Built using the api kindly provided by the nice people at madewithlove.be, this tool allows you to test whether your .htaccess file redirects the url's as you expect them to.
Simply enter a url and some htaccess rules and the 'Test' button will be activated. If appropriate, you can include the optional Referrer and/or Server Name fields. The resultant URL will appear right here after you click the button.
This feature allows you to simulate what happens when a url redirect occurs. The new url is passed through the .htaccess rules to check if the new url is changed further. It is not good practise for a url to be redirected more than once; if this is the case, you should rewrite the rules so all permutations of url are redirected to their correct destination in a single pass.
Here are a couple of examples:
Want to save your htaccess file so you can come back and work on it later, or share your work of art (science?) with others? Clicking the share button will generate a link (and copy it to your clipboard), so you can come back to it at a later date.
