Question

Currently I have clientCache Web.config cache which caches all statis content:

<staticContent>
      <clientCache httpExpires="Sun, 29 Mar 2020 00:00:00 GMT" cacheControlMode ="UseExpires"/>
</staticContent>

But I want to exclude favicon.ico from caching (or make it expiration date less). Is there any way to implement it?

Answer 1

Try adding <location> under <configuration> tag, specifying that it should be applied to that file only — something like this (just an example — taken from real working configuration, where favicon.ico has different expire time compared to all other files):

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
    ...
    <!-- your site config here -->
    ...
    </system.webServer>
    <location path="favicon.ico">
        <system.webServer>
            <staticContent>
                <clientCache cacheControlMode="UseMaxAge" cacheControlMaxAge="366.00:00:00" />
            </staticContent>
        </system.webServer>
    </location>
</configuration>
