Hi,
I'm using Rack::Sendfile (via Rails) and was wondering if someone could
explain if what I'm experiencing is deliberate, or could be changed.
I've noticed when nginx adds the header "X-Sendfile-Type:
X-Accel-Redirect", then Rack::Sendfile will jump into action. If the header
"X-Accel-Mapping" is missing then it will not interfere. However, if both
of the headers are present it will take over - even if the mapping cannot
be resolved.
This doesn't make sense to me, as if the X-Accel-Mapping does not match the
path of the file that is being attempted to send, then surely Rack:Sendfile
should not interfere so that the file can be sent successfully albeit
less efficiently?
Cheers
Theo
