Question

I use Asp.net 4 c# and Page OutPut Cache IN MEMORY for optimizing performances.

For my understanding all the HTML generated by Server Controls will be cached for my page (in memory).

If in my Web Page I use references to CSS and JAVASCRIPT Files, example Google Adsense or others.

How Page OutPut Cache behaves?

Even my JAVASCRIPT will be cached?

Thanks for your time.

Answer 1

Page level, or output caching, caches the HTML output of dynamic requests to ASP.NET Web pages

With output caching, the final rendered HTML of the page is cached. When the same page is requested again, the control objects are not created, the page life cycle doesn’t start, and none of your code executes. Instead, the cached HTML is served. Clearly, output caching gets the theoretical maximum performance increase, because all the overhead of your code is sidestepped.
