hi,  
i tested a cast, a third modul which can echo ‘helloworld’, it could  
work well at 0.7.65 version. i tried to add this module into the 1.0.8  
version nginx. it could configure well and build well, but when i run  
the nginx, it told me:  
nginx: [emerg] unknown “uid\_reset” variable

i found that the “uid\_reset” is a new feature of 1.0.5. what do i need  
to do to make it work well at 1.0.8 verion?
