nginxUsing if else condition

Here we use temporary $test variable to emulate if-else functionality as Nginx doesn't support else:

server {
  set $test "notok";
  if ($http_cookie ~* "session") {
    set $test "ok";
  }
  
  if ($test = "ok") {
    return 200;
  }
  
  if ( $test = "notok" ) {
    return 403;
  }
}ctrl + cyoutubegithub

`set $test "notok"` set default value for `$test` variable	`if ($http_cookie ~* "session")` condition which we need `else` functionality for
`set $test "ok"` set `ok` value if condition is `true`	`if ($test = "ok") {` this condition will repeat our original condition to check
`if ( $test = "notok" ) {` this condition will pass if previous condition didn't pass - so the same as `else` functionality
