Thanks for the reply. See below for the server code I'm using.<div><br></div><div>I narrowed down the problem a bit and there are actually two different but related issues. The first is that request data is ignored for non-POST, non-PUT requests:</div> <div><br></div><div><font class="Apple-style-span" face="'courier new', monospace">$ curl <a href="http://localhost:8000">http://localhost:8000</a> -d "abcd" -X POST</font></div><div><font class="Apple-style-span" face="'courier new', monospace"><html><p><b>POST</b></p><p><b>abcd</b></p></html></font></div> <div><font class="Apple-style-span" face="'courier new', monospace"><br></font></div><div><font class="Apple-style-span" face="'courier new', monospace">$ curl <a href="http://localhost:8000">http://localhost:8000</a> -d "abcd" -X PATCH</font><div style="font-family: 'courier new', monospace; "> <html><p><b>PATCH</b></p><p><b>No request body</b></p></html></div><div style="font-family: 'courier new', monospace; "><br></div><div><font class="Apple-style-span" face="arial, helvetica, sans-serif">The second problem is that POST and PUT requests hang when no request body is specified:</font></div> <div><font class="Apple-style-span" face="arial, helvetica, sans-serif"><br></font></div><div><font class="Apple-style-span" face="'courier new', monospace">$ curl <a href="http://localhost:8000">http://localhost:8000</a> -X POST (hangs)</font></div> <div><font class="Apple-style-span" face="arial, helvetica, sans-serif"><span class="Apple-style-span" style="font-family: 'courier new', monospace; ">$ curl <a href="http://localhost:8000">http://localhost:8000</a> -X PUT (hangs)</span></font></div> <div><font class="Apple-style-span" face="arial, helvetica, sans-serif"><br></font></div><div><font class="Apple-style-span" face="arial, helvetica, sans-serif">No server errors, even after killing the request.

Request objects have a 'method' field that<br> you can look at it. The bindings are a promise so that non-form-data<br> POST content doesn't get erroneously parsed as bindings (unless you<br> force the promise). This is all in place so that you can implement<br> which ever methods you want without interference from the server's<br> default behavior. Can you post a small example that has the hanging<br> error?<br> <br> Jay<br> <div><div></div><div class="h5"><br> On Sat, Sep 10, 2011 at 8:12 PM, Daniel MacDougall<br> <<a href="mailto:dmacdougall@gmail.com">dmacdougall@gmail.com</a>> wrote:<br> > Hi,<br> > I'm trying to build a web server that responds to [POST/PUT/DELETE]<br> > requests.
