File contents are sanitized to avoid script execution be rogue content. For performance reasons, the sanitation takes place for requests where the MIME type indicates that the content will be displayed/executed within the browser context. While the most commonly used MIME-types are covered (text/html), some browsers also execute script code within files signalled with text/xml MIME-type.
