Redirect HTTP to HTTPS and HTTPS to HTTP

[Henri Storn]

Hello,

I have a server hosting multiple Web sites. I use HAProxy, Stunnel and 
HTTPD :

HTTP -> HAProxy (80) -> HTTPD (8080)
HTTPS -> Stunnel (443) -> HAproxy (8443) -> HTTPD (8080)

I want a single Web site is accessible via HTTPS. The others are only 
accessible by HTTP. I want to do the following redirects :
- http://server.domain.com/ -> https://server.domain.com/ [OK]
- https://other.domain.com/ -> https://other.domain.com/ [PROBLEM]

I can not create the ACL. Can you help me ?

listen http
        bind *:80
        acl url_admin hdr_beg server.domain.com
        redirect prefix https://server.domain.com if url_admin
        server srv 127.0.0.1:8080 maxconn 256

listen https
        bind 192.168.0.100:8443
        acl url_admin hdr_beg server.domain.com
        redirect prefix http://XXXXX unless url_admin
        option forwardfor except 192.168.0.100
        server srv 127.0.0.1:8080 maxconn 256


Thanks,

Regards.
