Hi,

I need to add a http header for my application.
But according to the man page, it seems only HTTPS Listener can manage
the stuff. Even though, it can only add static content for headers.

My situation is:
My backends rewrite urls according the request base url. Since I use
Pound as the frontend. The "HTTP-HOST" becomes meaningless. And the backends
support "X-Forwarded-Host".

So, how can I setup Pound, or I have to hack my backend?

I am rather confused: the request URL is passed through to the back-ends
unchanged, so it can be used exactly as without Pound. Perhaps you'd
like to explain again what the problem is?

As to the other things you seem to be asking:

- a header is added only for HTTPS because of the change in protocol.
This allows certain back-ends (such as OWA) to adjust their responses
accordingly.

- Pound uses X-Forwarded-for to tell the back-end the client's
originating address. You could use that if you want, though it is far
from reliable, can be easily faked, and may appear multiple times (once
for each proxy along the way).

Hope this helps some...[...]

Thank you for your reply.

I tested once more. It seems Pound has already added X-Forwarded-for and
X-Forwarded-Host
headers. But it is not mentioned in the doc that Pound will add headers
for HTTP. Am I missed something?

Anyway, it works now.

Hi

In Pound-1.10 have the line
   HeadRemove "X-Forwarded-For"
in my config files. The X-Forwarded-For added by pound is then the only 
X-Forwarded-For header in the request coming out of pound.

Pound-1.10 at least uses the inet_ntoa() function to convert the IP 
address to text, and the manpage for inet_ntoa states:

        The inet_ntoa() function converts the Internet host address in given in
        network  byte  order to a string in standard numbers-and-dots notation.
        The string is returned in a statically allocated buffer,  which  subse-
        quent calls will overwrite.

This means you should be careful in using this for authentication 
purposes, but it is ok for logging. There was a thread on the mailing list 
about this:
   http://www.apsis.ch/pound/pound_list/archive/2004/2004-10/1096989160000

I do not know if Pound-2.x uses the safer inet_ntop() now.

Regards
Rune
