Functions
Functions that are not part of a class:

sendFile($file, $mime, $dl, $cache, $public = false, $orig = null)   X-Ref
Set headers and send the file to the client

The $cache parameter influences how long files may be kept in caches, the $public parameter
influences if this caching may happen in public proxis or in the browser cache only FS#2734

This function will abort the current script when a 304 is sent or file sending is handled
through x-sendfile

param: string $file   local file to send
param: string $mime   mime type of the file
param: bool   $dl     set to true to force a browser download
param: int    $cache  remaining cache time in seconds (-1 for $conf['cache'], 0 for no-cache)
param: bool   $public is this a public ressource or a private one?
param: string $orig   original file to send - the file name will be used for the Content-Disposition

rfc2231_encode($name, $value, $charset='utf-8', $lang='en')   X-Ref
Try an rfc2231 compatible encoding. This ensures correct
interpretation of filenames outside of the ASCII set.
This seems to be needed for file names with e.g. umlauts that
would otherwise decode wrongly in IE.

There is no additional checking, just the encoding and setting the key=value for usage in headers
