gistfile1.js

/* 
 * showed in chrome network posted the same value and returned the same response
 * the following code will call action "getBar" twice
 * $.post("example.com",{action:'getFoo'},function(data){},"json");
 * $.post("example.com",{action:'getBar'},function(data){},"json");
 * 
 * in google chrome network tab, it will show that getFoo is ignored and getBar was called twice, though
 * the object response are correct on the javascript end.
 * 
 * work around to this bug:
 */
$.post("example.com?foo",{action:'getFoo'},function(data){},"json");
$.post("example.com?bar",{action:'getBar'},function(data){},"json");
