💡 Hint

Common Mistakes

Using percentages that do not add up to 100%

Not using semicolons to separate variant assignments

The split_clients directive assigns users to variants based on the client IP. Here, 50% of users get variant A and 50% get variant B.

Complete the code to set a variable 'color' for A/B testing with split_clients.

Nginx

split_clients "$http_user_agent" $color {
    [1];
}

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

A30% red; 70% blue

B80% orange; 20% purple

💡 Hint

Common Mistakes

Using incorrect syntax without semicolons

Percentages not summing to 100%

This splits users based on their user agent string, assigning 30% to 'red' and 70% to 'blue'.

3fill in blank

hard

Fix the error in the split_clients block to correctly assign variants.

Nginx

split_clients "$cookie_user" $group {
    [1];
}

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

A50% groupA; 50% groupB

B50% groupA;50% groupB

C50% groupA, 50% groupB

D50% groupA 50% groupB

💡 Hint

Common Mistakes

Using commas instead of semicolons

Missing semicolons between assignments

The correct syntax requires semicolons to separate variant assignments with spaces after semicolons.

4fill in blank

hard

Fill both blanks to split traffic by IP and assign variants with weights.

Nginx

split_clients "$remote_addr" $test_group {
    [1];
    [2];
}

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

A20% control

Missing semicolons after assignments

The code assigns 20% of users to 'control' and 80% to 'experiment' groups based on IP.

5fill in blank

hard

Fill all three blanks to create a split_clients block with three variants.

Nginx

split_clients "$http_cookie" $variant {
    [1];
    [2];
    [3];
}
