If the download CGI parameter is true disposition is changed from inline to attachment, which will present a download dialog box in sane browsers.
Content-Length
The filesize value of the file object.
Content-MD5
The MD5 of the file content in base-64 encoding if the hash value is set and hash_type is MD5.
Content-Type
The mime_type value of the file object, or application/octet-stream if not set.
ETag
The hash value of the file object, if set.
Expires
The current time + 365 days, if the mtime value is set.
Last-Modified
The mtime of the file object, if set.
Accept-Ranges
Sets Accept-Ranges to bytes.
Recognised HTTP Headers
The following headers are recognised by this module.
If-Modified-Since
If greater than or equal to the mtime value of the file object returns 304 Not Modified.
If-None-Match
