a while ago I sent an email inquiring about nginx feature equivalent to mod_secdownload of Lighttpd found here (http://trac.lighttpd.net/trac/wiki/Docs%3AModSecDownload)

recently I checked the feature request page of nginx wiki and found a suggestion to use NginxXSendfile feature; however I'm not sure if XSendfile supports the following

the uri expires; timing out,

static file is on a URI on a different machine/location

these two parameters of the mod_secdownload are very valuables, they allow me to give someone a limited access to a static file, then later, if his/her membership expires, they no longer can use the same old uri to access the static file.

I could be wrong, but is what I just described is lacking from XSendfile feature??
