/**
 * 
 * Example of sending Different requests to same target server. note that the target host must
 * match the key: e.g. hitting
 * http://www.parallec.io/userdata/sample_weather_48824.txt
 * http://www.parallec.io/userdata/sample_weather_95037.txt
 * 
 * You may fire thousands of APIs to the same server in this way.
 * 
 * This is the easiest way to conduct variable replacement (only 1 variable)
 * more complex examples are in the test cases:
 * https://github.com/eBay/parallec/blob/master/src/test/java/io/parallec/core/
 * main/http/request/template/ParallelClientVarReplacementHostSpecificTest.java
