MVC4 Script Bundles Caching issue

We have an MVS application where we are bundling the javascript code using Bundle class ( don't do minification).

Bundling just works fine, but when we run the application, Cache value is set to Cache-Control:no-cache and at the same time every time we refresh the page the request always has a 200 OK. This means the js is not getting cached on client even though nothing was changed.

Also is there a way to verify if the bundled js is built dynamically or getting it from server cache?

Thanks

Solution

  • The problem appears to be with the Microsoft.AspNet.Web.Optimization NuGet package. After downgrading the version from 1.3.0 to 1.1.0, everything seems to be working fine.
