Editing URL redirection (section)

=== JavaScript redirects ===
[[JavaScript]] can cause a redirect by setting the <code>window.location</code> attribute, e.g.:
<syntaxhighlight lang="javascript">
window.location='https://www.example.com/'
</syntaxhighlight>
Normally JavaScript pushes the redirector site's [[URL]] to the browser's history. It can cause redirect loops when users hit the back button. With the following command you can prevent this type of behaviour.<ref name="knBmq" />
<syntaxhighlight lang="javascript">
window.location.replace('https://www.example.com/')
</syntaxhighlight>
However, HTTP headers or the refresh meta tag may be preferred for security reasons and because JavaScript will not be executed by some browsers and many [[web crawler]]s.
