Subject RE: [users@httpd] Passing remote client IP address to backend server and session stickness
Date Tue, 01 Dec 2009 15:32:11 GMT
Hi, Haroon

I read http://en.wikipedia.org/wiki/X-Forwarded-For yesterday and I did not see Apache listed
there. I saw squid, bluecoat, etc. listed there so I was thinking to test squid with the feature.
What is your suggestion? Thanks.

Ryan

Hi Ryan,

X-Forwarded-For is not a statement that goes inside the httpd.conf. The 
documentation page is just telling you that these headers are already 
available to you, if you are using reverse-proxy.

So, don't put the X-Forwarded-For statement there.

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,
