title: IIS server blocking access to .webp files
body: <p>So I'm trying to add .webp image support for a WordPress site, which is run on IIS.</p>
  
  <p>Now the image exists on the server and the file name is correct but when I try to load the image via URL address in the browser I get the 404 error.</p>
  
  <blockquote>
    <p>404 - File or directory not found. The resource you are looking for
    might have been removed, had its name changed, or is temporarily
    unavailable.</p>
  </blockquote>
  
  <p>Anyone know how I might resolve this issue?</p>
  
  <p>I tried added <code>&lt;add extension=".webp" policy="CacheUntilChange" kernelCachePolicy="DontCache" /&gt;</code> but this doesn't work as it's to do with caching.</p>
  
  <p>Is there somewhere were I can allow access to certain file types?</p>
  
  <p>Do I maybe need to allow the filetype through the firewall?</p>
  
  <p>I'm still new to working with IIS so I'm a little lost.</p>
  
  <p>Cheers</p>
