Issues with testing static content caching using Fiddler

I have implemented static content caching on the Images folder in our application by creating the below Web.config file in the Images folder:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <staticContent>
            <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="365.00:00:00" />
        </staticContent>
    </system.webServer>
</configuration>

I believe this has the effect of caching all the images on the client side for 365 days.

I tested the caching using fiddler by examining the response headers.

Initially, I was able to see headers for all files in the Images folder to have a max-age value of

Cache-Control: max-age=31536000

However, suddenly today I was not able to see it.

There have been no changes to the code or config.

Can someone please shed some light on why this is happening and how I can better test if caching is correctly working?

Thanks, Rashmi
