YSlow: Use GET for AJAX requests

Overview

Use GET rather than POST to collate headers and data.

How does your site score on this recommendation?

Details from Yahoo!

When using the XMLHttpRequest object, the browser implements POST in two steps:

  1. send the headers, and..
  2. send the data.

It is better to use GET instead of POST since GET sends the headers and the data together (unless there are many cookies). IE's maximum URL length is 2 KB, so if you are sending more than this amount of data you may not be able to use GET.
