💡 Hint

Common Mistakes

Using a path unrelated to API like /home or /static.

The location block should match the API path /api to route requests correctly.

2fill in blank

medium

Complete the code to proxy API requests to the backend server.

Nginx

location /api {
    proxy_pass [1];
}

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

Bhttp://localhost:80

Chttp://backend_api

Dhttps://external_site

💡 Hint

Common Mistakes

Proxying to the frontend or unrelated servers.

The proxy_pass should point to the backend API server to forward API requests.

3fill in blank

hard

Fix the error in the location block to correctly match all API requests including subpaths.

Nginx

location [1] {
    proxy_pass http://backend_api;
}

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

A/api/*

B/api

C~ /api

D/api/

💡 Hint

Common Mistakes

Using regex (~) without proper syntax or using wildcard * which is invalid in location.

Using /api/ ensures that all requests starting with /api/ including subpaths are matched.

4fill in blank

hard

Fill both blanks to rewrite the URL path before proxying to backend.

Nginx

location /api/ {
    proxy_pass http://backend_api[1];
    rewrite [2] $1 break;
}

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

A/v1/

B^/api/(.*)$

C/

D/v1

💡 Hint

Common Mistakes

Using trailing slash in proxy_pass causing double slashes.

Incorrect regex in rewrite directive.

The proxy_pass appends /v1 to the backend URL. The rewrite uses regex to capture the path after /api/.

5fill in blank

hard

Fill all three blanks to create a location block that proxies /api requests to backend and sets a custom header.

Nginx

location [1] {
    proxy_pass [2];
    proxy_set_header [3] "API-Request";
}

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

A/api/

Bhttp://backend_api

CX-Custom-Header

D/api

Attempts:

3 left

💡 Hint

Common Mistakes

Missing trailing slash in location causing partial matches.

Wrong header name or missing proxy_pass.

The location block matches /api/, proxies to backend_api, and sets a custom header X-Custom-Header with value API-Request.
