conditional within an "if" in Nginx

Question

Is it possible to do more than one comparison within an “if” in Nginx? For instance in a language like JAVA we use “if(comparison 1 || comparison 2)” and the || works as an “or”

AlexeyPortnov · Answer

Using so many ‘if’ is bad practice and in most case means misunderstanding of nginx way configuration, the real power of nginx. Regardingif ($request_uri = /) {} Writing such statement means you do not understand nginx ‘location’ directive.Location is already optimized for checking $request_uri againt expressions. It works faster and safer. So your statement can be replaced with more properlocation = / {} Regarding other ‘if’ - in most cases it can be reduced with nginx ‘map’.This statement: if ($host ~* zencocoon.com ) {set $test “${test}+zencocoon.com ”;} if ($http_cookie !~* "auth_token") { set $test "${test}+no_auth_token"; } if ($test = "root+zencocoon.com+no_auth_token") { proxy_pass http://www.zencocoon.com; break; } Can be rewritten with map “$hostname:$http_cookie” $pass_to_proxy {default 0;“~*zencocoon.com :?!auth_token” 1;} if ($pass_to_proxy) {proxy_pass http://www.zencocoon.com ;break;} It’s more short, safe, elegant and nginx-way.

You can also use something like: if ($request_uri = /) { set $test "root"; } if ($host ~* zencocoon.com) { set $test "${test}+zencocoon.com"; } if ($http_cookie !~* "auth_token") { set $test "${test}+no_auth_token"; } if ($test = "root+zencocoon.com+no_auth_token") { proxy_pass http://www.zencocoon.com; break; } Taken from https://gist.github.com/jrom/1760790
