Caching WCF javascript proxy on browser

, 4 Apr 2012 CPOL
WCF Javascript Proxies (Service.svc/js) are never cached. They get generated and downloaded on every page view thus increasing page download time and server CPU. Here's an HttpModule to cache WCF Javascript Proxy on browser and respond with HTTP 304, if unchanged.
