💡 Hint

Common Mistakes

Using seconds instead of minutes like '30s'.

Setting too long cache time like '1h' when 10 minutes is required.

The directive proxy_cache_valid sets how long responses with status 200 are cached. Here, 10 minutes is the correct duration.

💡 Hint

Common Mistakes

Using 200 instead of 404.

Using 301 which is a redirect status.

The proxy_cache_valid directive can specify different cache times for different HTTP status codes. Here, 404 means 'Not Found' responses are cached for 1 minute.

💡 Hint

Common Mistakes

Using 'all' or 'every' which are not valid keywords.

Using 'all_status' which is not recognized.

The correct keyword to cache all response statuses in nginx is any. Other options are invalid and cause errors.

💡 Hint

Common Mistakes

Using 404 or 500 which are not redirects.

Mixing the order of status codes.

301 and 302 are HTTP redirect status codes. Setting cache validity for both to 30 minutes helps cache redirects properly.

💡 Hint

Common Mistakes

Using 500 instead of 'any' for the last blank.

Mixing the order of status codes.

This configuration sets different cache times for successful responses (200), not found errors (404), and all other statuses (any).
