<p>Rewrite has no problem. It doesn't dictate a verb that the client should use. The user-agent you're using is choosing to do this, possibly correctly, upon receipt of the 301 response.</p>
<p>Have a read of the 301, 302, 303, 307 and 308 sections here for more information: <a href="http://en.wikipedia.org/wiki/List_of_HTTP_status_codes#3xx_Redirection">http://en.wikipedia.org/wiki/List_of_HTTP_status_codes#3xx_Redirection</a></p>
<p>Your options appear to be to use an experimental response code, or to enforce that clients POST to the correct port. I'd choose the latter if at all possible.</p>
