Feature Request: New option "x-send-file-docroot"
<?php $file = "/etc/passwd"; header("Content-Type: text/plain"); header("X-LIGHTTPD-send-file: ".$file); flush(); exit(); ?>
Do i need more explanation ?
"allow-x-send-file" => "enable" is a very good feature, but its a little bit too powerful. So, it would be nice to restrict this function to a separate doc-root (or the same as the doc-root of the specific vhosts)
P.S: Excuse my english, i am german (nobody is perfect ;))
handle X-Sendfile and X-LIGHTTPD-send-file w/ http_response_xsendfile()
if host is configured ( "x-sendfile" = "enable" )
Note: X-Sendfile path is url-decoded for consistency, like X-Sendfile2
(response headers should be url-encoded to avoid tripping over
chars allowed in filesystem but which might change response
header parsing semantics)
Note: deprecated: "allow-x-send-file"; use "x-sendfile"
Note: deprecated: X-LIGHTTPD-send-file header; use X-Sendfile header
Note: deprecated: X-Sendfile2 header; use X-Sendfile header
For now, X-Sendfile2 is still handled internally by mod_fastcgi.
Since http_response_send_file() supports HTTP Range requests,
X-Sendfile2 is effectively obsolete. However, any code, e.g. PHP,
currently using X-Sendfile2 is probably manually generating 206 Partial
Content status and Range response headers. A future version of lighttpd
might *remove* X-Sendfile2. Existing code should be converted to use
X-Sendfile, which is easily done by removing all the special logic
around using X-Sendfile2, since the 206 Partial Content status and Range
response headers are handled in http_response_send_file().

/etc/passwd is more or less not critical. at least on linux. /etc/shadow is more critical. but that should be root only. whoever runs his webserver as root should be shot in the first place.
anyway.... x-sendfile has other problems. what if the user creates a php script that symlinks /etc/shadow into his docroot?
i personally would say: only enable x-sendfile for trusted scripts. on mass hosting environments i would leave it off. And i really wonder if a check like that would put us on the same road as php's open_basedir.
jan do we want that? at the first sight, the code for that looks trivial.
