easy

Complete the code to set the client header buffer size to 8k.

Nginx

client_header_buffer_size [1];

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

💡 Hint

Common Mistakes

Using a size smaller than needed causing header truncation.

Forgetting the 'k' suffix for kilobytes.

The client_header_buffer_size directive sets the buffer size for reading client request headers. Setting it to 8k allocates 8 kilobytes for this buffer.

Complete the code to set the large client header buffers to 4 buffers of 16k each.

Nginx

large_client_header_buffers [1] [2];

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

💡 Hint

Common Mistakes

Swapping the number and size values.

Using sizes without the 'k' suffix.

The large_client_header_buffers directive sets the number and size of buffers for large headers. Here, 4 buffers of 16k each are allocated.

Fix the error in the buffer size directive to use a valid size.

Nginx

client_body_buffer_size [1];

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

💡 Hint

Common Mistakes

Using plain numbers without units (interpreted as bytes, often too small).

Using invalid units like 'b' for bytes.

The client_body_buffer_size directive requires a valid size format. 512k means 512 kilobytes and is valid. 2048b is invalid because nginx does not recognize 'b' as a valid unit. Plain numbers like 1024 are valid (bytes) but typically too small for body buffers.

4fill in blank

hard

Fill both blanks to configure buffer sizes for client headers and body.

Nginx

client_header_buffer_size [1];
client_body_buffer_size [2];

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

💡 Hint

Common Mistakes

Setting body buffer smaller than header buffer.

Using inconsistent units.

Setting client_header_buffer_size to 8k and client_body_buffer_size to 16k allocates appropriate buffer sizes for headers and body respectively.

5fill in blank

hard

Fill all three blanks to set large client header buffers with 4 buffers of 8k each and client body buffer size to 16k.

Nginx

large_client_header_buffers [1] [2];
client_body_buffer_size [3];

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

💡 Hint

Common Mistakes

Mixing up the number of buffers and buffer size.

Using inconsistent or missing units.

This configuration sets 4 buffers of 8k each for large client headers and a 16k buffer for the client body, optimizing memory usage for large requests.
