+Supporting browser-based PUT & DELETE
+=====================================
+
+> "There are two noncontroversial uses for overloaded POST.  The first is to *simulate* HTTP's uniform interface for clients like web browsers that don't support PUT or DELETE" - [RESTful Web Services](1), Leonard Richardson & Sam Ruby.
+
+This is the same strategy as is used in [Ruby on Rails](2).
+
+Overloading the HTTP method
+---------------------------
+
+For example, given the following form:
+
+    <form action="/news-items/5" method="POST">
+	    <input type="hidden" name="_method" value="DELETE">
+	</form>
+
+`request.method` would return `"DELETE"`.
+
+Overloading the HTTP content type
+---------------------------------
+
+Browser-based submission of content types other than form are supported by using form fields named `_content` and `_content_type`:
+
+For example, given the following form:
+
+    <form action="/news-items/5" method="PUT">
+	    <input type="hidden" name="_content_type" value="application/json">
+		<input name="_content" value="{'count': 1}">
+	</form>
+
+`request.content_type` would return `"application/json"`, and `request.content` would return `"{'count': 1}"`
+
+Why not just use Javascript? 
+============================
+
+**[TODO]**
+
+Doesn't HTML5 support PUT and DELETE forms?
+===========================================
+
+Nope.  It was at one point intended to support `PUT` and `DELETE` forms, but was later [dropped from the spec](3).  There remains [ongoing discussion](4) about adding support for `PUT` and `DELETE`, as well as how to support content-types other than form-encoded data.
