Confirming HTTP caching with Fiddler

Question

How can I use Fiddler to confirm that HTTP caching is working? Is there another better way?

Answer 1

You can confirm caching by having a page fetch a resource and note that no request for the resource appeared in Fiddler. I can't think of a better way to do it. Works for me.

Answer 2

right click the URL in the fiddler and click properties, you can check the cach info in that popup under "WININET CACHE INFO"

Answer 3

Browse the site through the Fiddler as proxy. In each response details, there's a tab "Caching". This shows useful info about the response headers - e.g. what the different Cache-Control and Expires values mean.
