I saw some nginx configs written like this:

location ~ {  
…  
proxy\_pass [http://upstream1](http://upstream1);  
proxy\_pass [http://upstream2](http://upstream2);  
…  
}

What this config meaning? proxy\_pass to upstream2 if proxy\_pass to  
upstream fails?

Thanks.

nginx currently does not report this is as error.

effect?
