When do we use Cache-Control: public ?

[Amtoj]

Hi I have a website which has some images and someone has suggested me to use 'Cache-Control: public" for my images but I couldn't get his explanation over to why use it ?

So plz can u guys help me out to understand it better ?/

Here's what the W3C says:

public - Indicates that the response MAY be cached by any cache, even if it would normally be non-cacheable or cacheable only within a non- shared cache.

Generally, you don't need to declare this attribute in your Cache-Control header.
