Never tried instantiating conditions from javascript ...
But basically these are java classes.
So instantiate and set configure it
myhttp = new Http();
myhttp.setUrl("a url adress");
Maybe we could set a project instance or something like that.
Let's have a look at the sources [1,2] - yes. Http extends ProjectComponent.
So set the project reference so that Http could access properties and the
logger system.
myhttp.setProject( self.getProject() );
Then use the condition [3]
if (myhttp.eval()) {...
I havent tested these lines, so maybe you have to tweak javascript a little bit.
