Sometimes my request comes in as HTML and other times as TEXT/*. Why?

Question

I have an AJAX upload action for my Rails app. Sometimes it comes in as:

Started POST "/products/temp_upload" for 63.148.78.244 at Fri Sep 24 21:34:27 +0000 2010
  Processing by ProductsController#temp_upload as HTML

And everything runs smoothly.

Other times it comes in as:

Started POST "/products/temp_upload" for 63.148.78.244 at Fri Sep 24 21:49:35 +0000 2010
  Processing by ProductsController#temp_upload as TEXT/*

And I get a 406.

The only consistency I see is that it works on Windows and fails on OS X. Does anyone know why this is and how to fix it?

Thanks!

Answer 1

This means the browser making the request will accept all text response formats
