Hi,
As far as I know, we can't identify the requests cached or not from any web log. However, you can view the HTTP response cache by using netsh:
Run the following command from a command prompt
netsh http show cache
You can also adjust the Caching settings to control the page output cache
Caching <caching>

Below is a KB article about kernel-mode cache, hope helpful for you:
