redirect for all non-https except 1

[Peter Butler]

I am trying to redirect all HTTP to HTTPS except for 1 site.
The below redirects everything because redirect are processed before 
use_backend.

part of my issue is i have heaps of sites requiring HTTPS, and use 
*.wildcard certs, and like the simplicity of it.  So would prefer not to be 
listing all sites specifically in the config, just the one I want to keep on 
http

Any ideas please.



frontend unsecure 10.0.0.1:80
   mode http
   acl is_http-site_org_au hdr_end(host) -i www.site.org.au
   acl is_http-site_org_au hdr_end(host) -i site.org.au
   use_backend http_site_org_au if is_http-site_org_au


Things I have tried.
  #redirect scheme https code 301 if !is_www_site_org_au
  #redirect scheme https code 301 if !{ hdr(Host) -i www.site.org.au } !{ 
ssl_fc }
  #redirect scheme https code 301 if !{ ssl_fc }  !is_www_site_org_au



backend http_site_org_au
   mode http
   option tcp-check
   server site-02 10.1.1.1:80 check
