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”

In general, if statements should be avoided when possible, particularly inside location blocks. From the aptly titled “If Is Evil”:
As to your specific question, you can leverage regex to have multiple matches in the condition but not multiple conditions. So you can do something like:
but not:
There are some workarounds using multiple if statements. Check out this post.
Using so many ‘if’ is bad practice and in most case means misunderstanding of nginx way configuration, the real power of nginx.
Writing such statement means you do not understand nginx ‘location’ directive. Location is already optimized for checking $request_uri againt expressions. It works faster and safer.
So your statement can be replaced with more proper location = / { }
if ($host ~* zencocoon.com) { set $test “${test}+zencocoon.com”; }
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.
