Ajax error: Request-URI Too Large

I'm getting this ajax error msg: Ajax error: Request-URI Too Large

Does anyone know what is causing it?

I'm saving data in a textarea component to a file when this happens. I can load php files into my textarea fine and then save it back out on the server and I don't get this error. But if I try and load a .js file into my textarea and save that I get the error. I've had this appear a few times on non .js files but it mostly happens with a .js file.

Thanks for any help...

Sounds like you need to be using post and not get.
