Load modules using moduleLoader url property?

Question

My requirement is to load a module using URL like following
'/somthing.swf?a=b&b=c'
so that it can load the module and set a few values after it is loaded. But when i create an instance of the moduleLoader and set the Url property nothing is happening. My code is as follows
                        url += constructUrl()+"?"; // something like 'modules/vst/visitModule.swf' will be returned
               if(_modLoader){
                    _modLoader.addEventListener(ModuleEvent.READY,readyMod);
                    _modLoader.addEventListener(ModuleEvent.ERROR,loadError);
                    _modLoader.addEventListener(ModuleEvent.PROGRESS,loadProgress);
                    _modLoader.addEventListener(ModuleEvent.UNLOAD,unload);
                    _modLoader.applicationDomain = ApplicationDomain.currentDomain;                    
                    _modLoader.url = url;
Do you see something wrong here? I'm using Flex 3.2.
I've read in the following forum for the solution http://forum.springsource.org/archive/index.php/t-65228.html but could not get it to work. Still trying.
Thanks

Well the if statement guarding the loadModule() call looks like this:
        if (_url != null && loadRequested)
            loadModule();
Assuing url is not null, loadRequested must be false. This seems to imply that you don't have ModuleLoader declared in an mxml file. Is the ModuleLoader created using actionscript? If so you need to call loadModule().
