Encoded slashes in URL with proxy = trouble?

[François Beausoleil]

Hi!  

Nginx is in front of the RabbitMQ management extension. Some of the URLs the extension generates contain en embedded slash character (%2F):

 http://somehost/#/queues/%2F/events

The encoded slash represents the vhost I want to get information about. I found an older ServerFault question with no answer[1], and was wondering if any of you had a way to let Nginx pass through the encoded slash?

Thanks!
François
