AJAX Service 'Proxies' Not Cached

Hi All,

We are consuming WCF services from javascript using ASP.Net AJAX. I have noted that the JavaScript proxy files (i.e the *.svc/js files) are not being sent with an 'If-Modified-Since' header and are thus not being cached by the browser. Does anyone have any insight in to why? If this is 'by design' does anyone know how this behavior can be changed? It's crap for performance.

 

Thanks,

mal
