How can I redirect 404 (bad url) to the homepage?

To redirect a 404 error page to the homepage, you can use a .htaccess file on an Apache web server or modify the web.config file on an IIS server. Here's how to do it:

Apache web server:

1. Create or edit your .htaccess file in the root directory of your website.
2. Add the following line of code at the end of the file:ErrorDocument 404 /index.phpThis assumes that your homepage is called index.php. If your homepage has a different name, replace "index.php" with the appropriate filename.
3. Save the changes to your .htaccess file and upload it to your web server.

IIS web server:

1. Open the web.config file in the root directory of your website.
2. Add the following code within the <system.webServer> tags:<httpErrors errorMode="Custom"> <remove statusCode="404" subStatusCode="-1" /> <error statusCode="404" prefixLanguageFilePath="" path="/" responseMode="Redirect" /> </httpErrors>
3. Save the changes to your web.config file and upload it to your web server.

With either of these methods, when a user tries to access a page that doesn't exist on your website, they will automatically be redirected to your homepage.
