HTTP::redirect uses the HTTP 302 status code to redirect a user agent to a new location, however when a user agent receives a HTTP 302 status code for a POST/PUT/DELETE HTTP request, it will use GET because it assumes the server received the data.

If you want to redirect the user agent and it should again issue a POST you would need to use HTTP status code 307, which will instruct the user agent to POST again to a different location.

HTTP::redirect only supports 302, so you would need to craft a HTTP redirect with HTTP::respond. Example:

HTTP::respond 307 Location "http://$orig_host$orig_uri/"
