Add "304 - Not Modified" (browser caching) for all files served by Vosao #497

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
I think it would be a good idea to add browser caching to any file (such as an 
image, css, js file) served by Vosao. This should reduce the load, increase the 
speed, reduce bandwidth consumption and increase page rank (Google factors in 
page load speed, and browser caching is one of the checks).

Would it be also possible to set the expiry time for it too?

By the way, apache (and most HTTP servers) do 304 by default. I found out that 
Vosao doesn't do it when I ran the google page speed checker.

Shouldn't be too hard to implement for static resources like those mentioned 
above right? Not overly concerned about pages being cached, just big resources 
like images and js.

Possible the problem in locale. There is a logic for cache control. It check 

if(DateUtil.toHeaderString(file.getLastModifiedTime()).equals(
                request.getHeader("If-Modified-Since"))){

But, request.getHeader("If-Modified-Since") maybe a non valid string format, 
e.g. ???, 17 ??? 2011...
