Error description
If a conditional request is made for resources and WCM is returning a 304 indicating that no change had occurred to the requested resource then we should also be sending back the "Expires" header to prevent the browser making the same request again when the page next reloads.
Local fix
E.g. If a spacer gif is used on all pages of a website then each page load will request this image. Having the resourceserver.browserCacheMaxAge set prevents browsers for re-requesting an image for the set amount of time. Once this time has been exceeded the browser will make a request to the server each time the image is encountered to check if it has changed. By sending back a new "Expires" value the browser will stop sending requests to the server.
