Dear List ,

I need to do a conditional proxy\_pass , but it’s not happening as  
expected  
.

like

set $target  
[http://www.example.com/sso/url.ping?TargetUrl=http://www.example.com/home](http://www.example.com/sso/url.ping?TargetUrl=http://www.example.com/home)

And that $target , I would like to check with $request\_uri in below  
segment  
.

location /sso/ {  
proxy\_set\_header X-Real-IP $remote\_addr;  
proxy\_set\_header X-Forwarded-For  
$proxy\_add\_x\_forwarded\_for;  
proxy\_set\_header Host $http\_host;  
proxy\_redirect off;  
----------  
if ($target ~ $request\_uri) {  
proxy\_pass [http://10.20.137.21](http://10.20.137.21);  
}  
else {  
return 403;  
}  
------------  
}

Is that possible achieve inside “location” for “proxy\_pass” .
