💡 Hint

Common Mistakes

Using GET or POST instead of PURGE will not remove cached content.

Using DELETE is not supported by nginx cache purging.

The PURGE method is used by nginx cache purging modules to remove cached content for a URL.

💡 Hint

Common Mistakes

Using proxy_cache_path instead of proxy_cache_purge disables purging.

proxy_cache_valid controls cache duration, not purging.

The directive proxy_cache_purge on; enables purging cached content in the specified location.

Fix the error in this nginx cache purge location block by completing the missing directive.

Nginx

location /purge/ {
    allow 127.0.0.1;
    deny all;
    [1] on;
}

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

Aproxy_cache_key

Cproxy_cache_purge

Dproxy_cache_methods

💡 Hint

Common Mistakes

Using proxy_cache_path or proxy_cache_key will cause errors or no purging.

Forgetting to allow local IPs will block purge requests.

The proxy_cache_purge on; directive is required to allow purging in this location block.

4fill in blank

hard

Fill both blanks to complete the nginx cache purge location that allows purging only from localhost and enables purging.

Nginx

location /cache/purge/ {
    [1] 127.0.0.1;
    [2] all;
    proxy_cache_purge on;
}

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

Dproxy_cache_path

Attempts:

💡 Hint

Common Mistakes

Reversing allow and deny directives.

Using proxy_cache directives instead of allow/deny.

The allow 127.0.0.1; permits localhost, and deny all; blocks others from purging.

5fill in blank

hard

Fill all three blanks to complete a dictionary comprehension that maps URLs to their cache purge commands.

Nginx

purge_commands = [1]: f"curl -X [2] http://localhost[3]" for [1] in urls if urls[[1]] == 'cache'

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

BPURGE

DGET

💡 Hint

Common Mistakes

Using GET instead of PURGE will not purge cache.

Using different variable names inconsistently.

This comprehension creates commands for URLs marked as 'cache' using the PURGE method.
