With our Windows hosting accounts, you can create caching rules to enhance your website's speed by using clientCache in your Web.config file.
Example
Microsoft uses the following example code in a Web.config to enable caching:
<configuration>
<system.webServer>
<staticContent>
<clientCache cacheControlMode="UseExpires"
httpExpires="Tue, 19 Jan 2028 03:14:07 GMT" />
</staticContent>
</system.webServer>
</configuration>
This will cache the content you define as static until Jan. 19, 2028.
