title: Major drawback of REST web service
body: <p>I am reading a Javascript book where it talks about web services but I find it hard to understand the following sentence as being a drawback of using REST (Representational State Transfer).</p>
  
  <blockquote>
    <p>One of the biggest drawbacks to using REST is that some browsers
    support only GET and POST methods, whereas many firewalls allow
    passage of only GET and POST methods.</p>
  </blockquote>
  
  <p>I don't really see how this is regarded as a drawback.
  English is not my 1st language so it could be just me finding it hard.</p>
  
  <p>Can someone elaborate on this?</p>
