I installed from the git head. For the callback status, it's: (:error (error http 405) :redirect https://bpaste.net/show/9f7b83e91ebc) For the callback buffer, it's: HTTP/1.1 405 METHOD NOT ALLOWED Server: nginx Date: Sun, 21 Feb 2016 10:45:21 GMT Content-Type: text/html Content-Length: 178 Connection: keep-alive Allow: HEAD, OPTIONS, GET X-Cache-Hits: 0 X-Cache-Age: 0 X-Cache-Status: MISS 405 Method Not Allowed

Method Not Allowed

The method is not allowed for the requested URL.

For the url-debug output, it's: https://bpaste.net/show/f5b3e99df8fd ***** So from the url-debug output, the logic is doing wrong. On Line#30, it's doing a *redirect* with post, resulting an HTTP 405. BTW, possible to do nothing other than firing up the callback when receiving the HTTP 302 on Line#32 ? Regards.
