💡 Hint

Common Mistakes

Using 'https' in the condition causes a redirect loop.

Using unsupported schemes like 'ftp' or 'ws'.

We check if the scheme is 'http' to redirect to HTTPS.

Common Mistakes

Checking for 'www.example.com' instead of 'example.com'.

Using a different domain like 'example.net'.

The condition checks if the host is 'example.com' to redirect to 'www.example.com'.

💡 Hint

Common Mistakes

Adding quotes or slashes around the regex pattern.

Using case-sensitive match (~ instead of ~*).

The pattern should be a plain string without quotes or slashes for the regex match.

💡 Hint

Common Mistakes

Using incorrect parameter names.

Checking for wrong values like 'new' instead of 'old'.

$arg_ref accesses the 'ref' query parameter, and we check if it equals 'old' to redirect.

5fill in blank

hard

Fill all three blanks to redirect requests from 'example.org' with user agent containing 'Bot' to '/botpage'.

Nginx

if ($host = [1]) {
    if ($http_user_agent ~* [2]) {
        return 302 [3];
    }
}

Drag options to blanks, or click blank then click option'

BBot

C/botpage

D/userpage

💡 Hint

Common Mistakes

Mixing up the host or user agent values.

Using wrong redirect URLs.

First check if host is 'example.org', then if user agent contains 'Bot', redirect to '/botpage'.
