nginx cookie - how to inject variable into cookie

[Payam Chychi]

Hey,

im trying to compare the cookie with  the remote_addr via nginx but
nginx sees $remote_addr as the text and not the a variable ... so it
wont match properly
I do have two cookies... the one I need to match for is the 2nd cookie
"YPF8827340282Jdskjhfiw_928937459182JAX666=96.48.77.222"

                if ( $http_cookie !~
YPF8827340282Jdskjhfiw_928937459182JAX666=$remote_addr ) {
                        rewrite  ^(.*)$  /check/$host.shtml  last;
                        break;
                }

2009/05/31 02:01:29 [debug] 1775#0: *6 http script regex:
"YPF8827340282Jdskjhfiw_928937459182JAX666=$remote_addr"

YPF8827340282Jdskjhfiw_928937459182JAX666=96.48.77.222", client:

HTTP/1.1", host: "www.whatwentwrong.org", referrer:

any ideas?

Thanks in advance
