Network.download URL Size Limit Help

I’m trying to make use of some webservices from my Corona app. The problem is that when I try and pass a long string in the url it gets truncated. For example: If I try and use the network.download method to pass and receive data to and from the web service it will work great if my url is not long. I need to be able to pass in a very long URL in order to pass all the data to the web service. Anyone knows a way around this?

network.download( “https://www.mysite.com/MyWebServices.aspx?myData=VeryBigStringHere”, “Post”, networkListener, “data.txt”, system.TemporaryDirectory )
