b24c77ceb4cea5ffa92536e19f0aa83608960dc4fielding <p>Files can have more than one extension; the order of the
c053576cdcd7389a1e11dd9c656f1f723ae854bcrbowen extensions is <em>normally</em> irrelevant. For example, if the

c14037646789087319802aaada2e8534ccab0158slive <code>welcome.fr.html</code> will map onto exactly the same

b24c77ceb4cea5ffa92536e19f0aa83608960dc4fielding the same type of metadata, then the one to the right will
c14037646789087319802aaada2e8534ccab0158slive be used, except for languages and content encodings. For example,
b24c77ceb4cea5ffa92536e19f0aa83608960dc4fielding if <code>.gif</code> maps to the <glossary>media-type</glossary>

c053576cdcd7389a1e11dd9c656f1f723ae854bcrbowen with the handler. For example, if the <code>.imap</code>
