💡 Hint

Common Mistakes

Using a very high burst value can cause server overload.

Omitting the burst option disables bursting.

The burst option sets how many requests can exceed the rate limit temporarily. Here, 5 means up to 5 extra requests can burst.

💡 Hint

Common Mistakes

Using 'delay' instead of 'nodelay' causes requests to be delayed.

Misspelling the option name.

The nodelay option makes requests exceeding the rate limit and burst limit processed immediately without delay.

💡 Hint

Common Mistakes

Writing numbers as words causes syntax errors.

Using values not supported by nginx.

The burst value must be a number, not a word. '5' is correct, 'five' or 'ten' are invalid.

💡 Hint

Common Mistakes

Swapping burst and nodelay positions.

Using 'delay' instead of 'nodelay'.

Use 5 for burst and nodelay to process excess requests immediately.

hard

Fill all three blanks to create a limit_req_zone and limit_req with burst and nodelay options.

Nginx

limit_req_zone $binary_remote_addr zone=mylimit:10m rate=[1];
limit_req zone=mylimit burst=[2] [3];

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

💡 Hint

Common Mistakes

Using incorrect rate format.

Omitting nodelay when bursts should be immediate.

The rate is set to 1r/s, burst to 5, and nodelay enables immediate processing of bursts.
