Hi, Haroon Thanks for the reply. Do you mean they are automatically activated for reverse proxy? Unfortunately it does not work for me if they are activated. My backend server will be Oracle 9iAS or Oracle 10gAS.

RJ> Thanks. RJ> For the backend server to be able to "see" the remote client IP, as if it was the real client IP, your application will have to be aware of the X-Forwarded-For. Depending on what technology you are using on the backend, the answer may be different about how to make your backend be aware of X-Forwarded-For header. Regardless of the technology, you probably should read up on the XFF entry at wikipedia: http://en.wikipedia.org/wiki/X-Forwarded-For And again, regardless of the tech, the HTTP request will contain the X-Forwarded-For header. On my java projects, I use xebia-france XForwardedFilter at: http://code.google.com/p/xebia-france/wiki/XForwardedFilter YMMV, RJ> RJ> Ryan RJ> Cheers, -- Haroon Rafique <haroon.rafique@xxxxxxxxxxx> --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
