nginx hack for multiple conditions

nginx.conf

    if ($request_uri = /) { 
      set $test  A; 
    } 
  
    if ($host ~* teambox.com) { 
      set $test  "${test}B"; 
    } 
  
    if ($http_cookie !~* "auth_token") { 
      set $test  "${test}C"; 
    } 
    
    if ($test = ABC) { 
      proxy_pass http://teambox-cms.heroku.com; 
      break; 
    } 

Thanks !

You are a god :D

Great solution! For those suggestion a map, that is great if condition variable remains the same for all checks. If not, this solution trumps map.

Thanks for this but I prefer to use @songsfromthewood map solution.

@songsfromthewood's example works great, with the exception of empty strings (like referer or useragent). But for blank referer and useragent, it's still pretty good :D

Hi All,

I am checking the header "x-token" present from the incoming request if not i have to send 403 in nginx below is my code

if ($http_x-token = ""){
return 403;
break;
}
proxy_pass http://127.0.0.1:1234;

But here "-" is the problem so how do i achieve this. if i pass the header as "xtoken" its working as expected
Could you please any one guide on this query.

Regards,
Naveen

nkn786, try $http_x_token.

You truly are the king of kings

awesome ! 666666

Nice. Thanks

Awesome man, thanks.

Seems, you are not familiar with map, or do not like it. More short and elegant:

":" is used just like delimiter, you can use any other symbol not used in checked variables.

map "$request_uri:$host:$http_cookie" $test {
    default 0;
    "/:teambox.com:auth_token"  1;
}

server {
    if ( $test ) {
      proxy_pass http://teambox-cms.heroku.com;
      break;
    }
}

@songsfromthewood Actually no, yours does not match "test.teambox.com" while the original post does.

this is awesome!

Need explanation.... what actually this does:
if ($host ~* teambox.com) {
set $test "${test}+teambox.com";
}
Does it takes "this".teambox.com or what? Thanks!

How to write this condition?

if ($host *.teambox.com) {
set $subdomain_name = ?;
}

Thanks!

Awesome!!!! Thanks!
If somebody needs an explanation what the code does is it sequentially appends different letters to one variable.
When all the letters are present that means that all the required conditions have been met.

This works great!

I recommend initializing the $test variable outside and above all the conditional statements to avoid endless using uninitialized "test" variable errors piling up in /var/log/nginx/error.log as follows:

set $test "";
