| Hi again, | |
| I stumbled across you "Forwarded http Extension" (http://tools.ietf.org/html/draft-petersson-forwarded-for-02) a week ago and have been thinking about it a bit more; One thing that I think the draft currently is missing is a way to disclose to the backend the full URL that was used for the original request. | |
| There are two things missing: | |
| Which resource was requested in the original request. If a request to http://myserver.com/hello/index.jsp is proxied to http://myserver.com/hello2/index.jsp it would be highly useful for the backend to know that the original request was /hello/index.jsp and not /hello2/index.jsp. While a frontend webserver could potentially correct redirects (301s and 302s, example: http://wiki.nginx.org/HttpProxyModule#proxy_redirect) there are also occasions when the backend would like to know about the original request being made. Examples are to have correct links/URLs to media files (images, CSS, JavaScript etc.). | |
| Which port that was used on the original request. While I hav |
