Hello,

Could somebody help me with a configuration question? I have two xrootd data servers:

Server A: no authorization needed. Anybody on site can access the data (readonly);

Server B: GSI authentication/authorization needed. 

If I want to put a xrootd redirector in front of the two data servers, is it possible for the redirector to redirect user requests to Server A first and only to Server B if the files are not available in Server A? All the data access are readonly, no writing. 

Thanks in advance for any advice on this.

Regards,

Yujun
