Lighttpd

Hello everybody，

Thanks a lot in advance if you will try to help me！

I encountered a issue when using lighttpd1.4.36 in Linux3.10.64. I set server.document-root to /pmc/work/air, but when I mount /pns/sdm_a/G4125.FGP to /pmc/work/air, lighttpd will access a file in the /pns/sdm_a directory. So,I would like to ask，how to prevent lighttpd from accessing folders other than server.document-root？

The following is the configuration information of lighttpd:

server.port = 80
$SERVER["socket"] == ":443" {
ssl.engine = "enable"
ssl.pemfile = "/etc/lighttpd/server.pem"
}

server.modules = (
"mod_accesslog",
)

server.errorlog = "/var/log/lighttpd.error"
accesslog.filename = "/var/log/lighttpd.access"

server.document-root = "/pmc/work/air"
index-file.names = ("index.html")

Any support is appreciated, thank you very much!
