Could you please give a minimal example that can reproduce this issue?

Apparently, the following example works as expected on my side with
ngx_lua 0.8.4 + nginx 1.4.1 on Linux x86_64:

location = /sub {
internal;
content_by_lua '
ngx.say("sr uri: ", ngx.var.uri)
';
}

location = /main {
echo_subrequest GET /sub;
}

Accessing /main with curl yields

$ curl localhost:1985/main
sr uri: /sub

That is, ngx.var.uri evaluates to the URI of the subrequest, /sub, not
that of the parent request, /main.
