MimeTypes#getMinLength(). If you set the offset value to larger
           than that size, the magic will only be compared to up to
           MimeTypes#getMinLength() bytes. It should also only start after
           the higher priority "start of file" one above
       -->
      <match value="&lt;html" type="string" offset="128:8192"/>
    </magic>
    <glob pattern="*.html"/>
    <glob pattern="*.htm"/>
  </mime-type>
