[Cppcms-users] xsendfile

[Markus R. <us...@ma...>]

Hi list!

I tried to use xsendfile to send files to the user from my cppcms
application. I succeeded with lighttpd using:

add_header("Content-Disposition: attachment; filename=\"" + my_path.leaf()
+ '"');
add_header("X-LIGHTTPD-send-file: " + root + "/" + file);

only adding the option
  "allow-x-send-file" => "enable"
in config file. (section $API.server)

But because of another bug I can't use lighttpd (at least the 1.4.*):
http://redmine.lighttpd.net/issues/show/729


So I tried the same with nginx - but without success. Maybe someone here can
help me?

add_header("X-Accel-Redirect: /Homepage/" + file)

leads to this sequence of requests[0], having in log[1].
Ok, does not surprise much, because it is not really a sendfile, but rather
a redirection feature (which can be misused to send files).

So I added:
         location /Homepage {
             root /home/markus/Projekte;
             internal;
         }
in the configuration inside server section. But this does not change
anything[0,1].

Seems like that rule is simply ignored, maybe because of the other locations
present in the config file? I directly changed cppcms_run to add that
config snippet. 


Any hints?

@Artyom: Do you plan to add sendfile support in the cppcms_run configs? At
least for lighttpd it is very easy.

thanks
