Hi,

I was trying to achieve for following url using nginx.

[https://localhost/xyz/d/\_0uzUTWZZw/message?orgId=1](https://localhost/xyz/d/_0uzUTWZZw/message?orgId=1)  
if such url requested contains string orgId then set some value to variable.

[https://localhost/xyz/d/\_0uzUTWZZw/message?orgId=1&var-id=2](https://localhost/xyz/d/_0uzUTWZZw/message?orgId=1&var-id=2)  
if such url requested contains string var-id then set another value to variable.

location /xyz/ {  
if ($request\_uri ~\* “/xyz/.+?orgId”){  
set $xyzuser TestingAuthUser1;   
}  
if ($request\_uri ~\* “/xyz/.+?orgId.+var-Id”){  
set $xyzuser TestingAuthUser2;   
}  
proxy\_set\_header X-WEBAUTH-USER “${xyzuser}”;  
}

How can I achieve this scenario in nginx. Please suggest.
