On a Windows 2008 R2, using DNS and IIS I've established my development test server; i.e. I'll have a web application that I can browse on http://test.dev
I've moved all the static
content files like images, js files and css files into another application which is visible on http://cdn.test.dev
test.dev, uses cdn.test.dev urls like http://cdn.test.dev/js/jquery.js to load js, css and images.
When I first load "~/" of test.dev, all files will load with a response code of 200; when I press F5 in Firefox, all files, except the "~/default.aspx", will load with 304 response code; but pressing Ctrl+F5 loads them again with a 200 code; if I browse another url like "~/pages/" in test.dev, all of those static files will reload with a 200 code... Is this normal or I'm doing something wrong?
Actually, I'm looking for a behavior like this:
I want the client to load http://cdn.test.dev/js/jquery.js, only once. I want the client's browser to use this jquery.js file, from cache, in all other pages of test.dev
Is this possible?
This is the web.config file I have in the root directory of cdn.test.dev:
