Webs_kit.Gateway
Gateway interaction.
See this section of the web service howto.
val send_file : header:Webs.Http.name -> Webs.Http.req -> Webs.Http.fpath -> (Webs.Http.resp, 'e) Stdlib.result
send_file ~header r file
lets the gateway respond to r
with file file
, use Req_to
.absolute_filepath to determine one from r
safely. More precisely this a Webs.Http.ok_200
empty response with:
header
set to file
. The actual header
to use depends on your gateway.Note. The gateway docs of this mechanism are unclear whether we should also transfer some of r
's headers in the response e.g. the etag and conditional headers but at least with Nginx that doesn't seem to be the case.
val x_accel_redirect : Webs.Http.name
x_accel_redirect
is the header name "x-accel-redirect"
used by Nginx for internal redirection.
val x_sendfile : Webs.Http.name
x_sendfile
is the header name "x-sendfile"
. Used by Apache and Lighttpd for file serving.
