Significance of "cacheSeconds"

[neeraj_cmu]

I couldn't find any documentation of the significance of 'cacheSecond'. I saw the comments on the example of 'sellItems'.

		<!--
			Set cacheSeconds to a small, non 0, value so you can do ctrl-N to open an new
			window and experiment with the continuations stuff.
		-->
		<property name="cacheSeconds" value="5"/>

Could someone elaborate this?

FlowController inherits it from WebContentGenerator.setCacheSeconds. It controls the caching headers sent to the browser.

The sellitem sample sets it to a small, non-zero value because having 0 will cause Internet Explorer to display the 'warning, form resubmission required' screen when you do CTRL-N to open a new window.
