hi all,  
today i put my nginx in production , listening on port 80.  
Requestes to www, pass-through proxy directive, will be sended to the  
localhost:82, where is the tomcat.  
Another site, blog.domain address is apache on the address localhost:81.

I installed the apache’s module rpaf and now I see in the logs IP  
addresses of users.

Is there any solution for the tomcat (6.x) to solve the problem too?

Thanks

here my default.conf

server {  
server\_name [www.domain.com](http://www.domain.com);  
location / {  
port\_in\_redirect off;  
proxy\_redirect off;  
proxy\_pass [http://localhost:82](http://localhost:82);  
proxy\_set\_header Host $host;  
proxy\_set\_header X-Real-IP $remote\_addr;  
proxy\_set\_header X-Forwarded-For  
$proxy\_add\_x\_forwarded\_for;  
proxy\_set\_header X-Forwarded-Host $host;  
proxy\_set\_header X-Forwarded-Port 80;  
}  
}

Is it an odd question?

Here it is the solution:

In server.xml, chanche the pattern"combined" of Log Valve, with this

pattern="%{X-Forwarded-For}i %l %u %t “%r” %s %b  
“%{Referer}i” “%{User-agent}i”"

This way you get the the various fields remain correctly grouped  
together when parsed.
