function url( value ) {
	return baseURL + value + ( /\?/.test( value ) ? "&" : "?" ) +
		new Date().getTime() + "" + parseInt( Math.random() * 100000, 10 );
}
Add random number to url to stop caching

Also prefixes with baseURL automatically.

@example url("index.html")
@result "data/index.html?10538358428943"

@example url("mock.php?foo=bar")
@result "data/mock.php?foo=bar&10538358345554"
