Browser Caching strategies

[Tony Evans]

Hi,

I am currently looking into Browser Caching strategies for browsers such as IE6 to IE9, Firdox chrome an so on.

We cant use nocache, but are looking at using Expires vs max-age, ETAG vs Last-modified.

I am looking for any good documentation or sites that would help me in my research.

So far with google I have got quite a lot of conflicting personal opinions.

Thanks for any help Tony

Well testing the browser in IE, FireFox Chrome, and Safari.

The following browser caching code worked.

if(cacheControl){
        	HttpServletResponse resp = (HttpServletResponse) response;   
        	resp.setHeader("Cache-Control",  "max-age=0,must-revalidate");  
        	//resp.setHeader("Expires", "Tue, 03 Jul 2001 06:00:00 GMT");            
        	resp.setHeader("Last-Modified", new Date(inputFile.lastModified()).toString());                        
        }
