Funny you say that because that's almost exactly the limit that I'm being cut off at. But problem there is I'm using POST not GET. I just think it's a limit I'm going to have to deal with. My reply below shows that I'm also having trouble if I take that line that's causing the failure and copy it into a text editor. The text editor can't handle it over 4K either. Once I split it into 3000 char chunks, it works fine. So, must just be a limitation I'm going to have to handle.
