Window attachURL

Hi,
I am using dhtmlxWindow.
and i am loading a jsp using attachURL method.
eg.myWindow.attachURL(“MyServlet.ads?action=something”)

But when i am sending a lot of data in url , it is not sending morever browser hanged.

What is the problem.

Is attachUrl method uses get or post?

If it is “post” then there wil be no issue I think attachURL uses get method?

1.how can i send post request using attachURL

2.What is the attachURL(url,true)… what second parameter use?

According to Documentation true indicates ajaxrequest, what it means?

Thanks ,
