Hello,
The <clientCache> element of the <staticContent> element specifies cache-related HTTP headers that IIS 7 and later sends to Web clients, which control how Web clients and proxy servers will cache the content that IIS 7 and later returns.
Open Internet Information Services (IIS) Manager: In the Connections pane, go to the site, application, or directory for which you want to disable caching. In the Home pane, double-click HTTP Response Headers.
Thank you,
