disqus update_thread HTTP method for this call must be POST

Recently I was trying to work with the Disqus comment system's API (version 1.1) and when trying to update infomation via the API, I kepy receiving:

 HTTP method for this call must be POST

In order to no longer recieve the error, I modified the URL I was posting to to end with a "/", for example:

http://disqus.com/api/update_thread/

That fixed the issue...
