[users@httpd] Wildcard-domain environment var for ProxyHTMLURLMap

[Florian S.]

Hi!

I got a question about how/where to use environment vars.

Assume a simple namebased VirtualHost that is a reverse proxy:

        Listen 127.0.0.1:1234
        NameVirtualHost 127.0.0.1:1234

        <VirtualHost 127.0.0.1:1234>
                ServerName *.foo.com
                ProxyPass / balancer://lb/
                ProxyPassReverse / balancer://lb/
        </VirtualHost>

        <Proxy balancer://lb>
                BalancerMember http://bar.com
        </Proxy>

Now, I want to sanitize the HTML and Location Headers. But how can I
determine, which domain matching the wildcard was used by the client?
(Host-Header like de.foo.com or en.foo.com)

It has to be something like that (simplyfied):
        
        ProxyHTMLURLMap bar.com %{HTTP_HOST}
        Header edit Location bar.com %{HTTP_HOST}

I found several different ways for giving env-vars or setting them for
myself first. Nothing worked.. (env:, ENV:, env=, %{}, %{}e, etc..)

Any ideas?

Thanks in advance:
