Hi,
what does cacheSeconds when we extend an Abstract Controller.
I found some explanation here -
http://docs.spring.io/spring/docs/2.5.x/api/org/springframework/web/servlet/mvc/AbstractController.html

But couldnt understand it. Please provide some example with explanation.

What is a cache header or header and its use ?

Thanks

This property indicates to the client how long for it should cache the content.

cacheSeconds = -1 means that no headers will be generated.
cacheSeconds = 0 means that no caching is allowed.
cacheSeconds > 0 means that the controller will send the appropriate headers to indicate that the content shall be cached for that many seconds.

For example with cacheSeconds = 0 the controller will send the following with the response

Pragma: No-cache
Expires: n (where n is the current system date + 30, as HTTP formatted date) (HTTP/1.0)
Cache-Control: no-cache (HTTP/1.1)
Cache-Controle: no-store (HTTP/1.1, for Firefox)

Open in new window


With cacheSeconds = 30 the controller will send the following with the response

Expires: n (where n is the current system date + 30, as HTTP formatted date) (HTTP/1.0)
Cache-Control: max-ages=30 (where the max-ages is the time the content should be cached for) (HTTP/1.1)

Open in new window


Note that the client might ignore all of these headers, so setting them hints to the client your intention, it does not instruct it.
