Jay,

Without touching your configuration files, I would say to setup a symlink.
ie
/home/sites/site1/web -- www.domain.com
/home/sites/site2/web -- www.domain.com.uk

now, using a symlink

cd /home/sites/site2
rmdir web
ln -s /home/sites/site1/web /home/sites/site2/web

There you can keep your original .uk and do NOT need to rewrite anything!

Subject: [cobalt-developers] Dynamically mirroring website


I am running a RaQ3 with multiple virtual domains hosted
on a single IP address.  I am trying to get two domains
to be identical, without rewriting the hostname URL.

User requests http://www.domain.com/foo.html
or user requests http://www.domain.co.uk/foo.html

I want both requests to return the exact same page from
my webserver (both domain names are hosted on the same
box and IP address).  Also I want the clicks on all relative
links to maintain the original hostname that they were
requested from (e.g., the UK user thinks they are still
in the UK as they click around the website).

I think the right answer is mod_rewrite rules using internal
proxy, but I gave server alias a whirl too.

1) Using ServerAlias gets the first page, but then the host
name changes if you click on anything:

<VirtualHost aa.bb.cc.dd>
ServerName www.domain.co.uk
ServerAlias www.domain.com
...
</VirtualHost>

2) I tried to use proxy but I can't get it to work.  I uncommented
the line    ProxyRequests on      and then did the following:

<VirtualHost aa.bb.cc.dd>
ServerName www.domain.co.uk
RewriteEngine on
RewriteCond %{HTTP_HOST}                !^aa.bb.cc.dd(:80)?$
RewriteCond %{HTTP_HOST}                !^www.domain.co.uk(:80)?$
RewriteRule ^/(.*)                      http://www.domain.com/$1 [P]

The [P] flag is supposed to make it use the internal proxy and
redirect to the external domain without modifying the URL.

Any ideas on how to make this work?

3) I tried the lame idea of just mapping my root directories (which
of course won't work when I use multiple machines), but
for some reason the httpd thinks that the first virtual domain takes
precedence, gives me a warning and never sets up properly:

<VirtualHost aa.bb.cc.dd>
ServerName www.domain.co.uk
# DocumentRoot /home/sites/site7/web
DocumentRoot /home/sites/home/web
RewriteEngine on
RewriteCond %{HTTP_HOST}                !^aa.bb.cc.dd(:80)?$
RewriteCond %{HTTP_HOST}                !^www.domain.co.uk(:80)?$
RewriteRule ^/(.*)                      http://www.domain.co.uk/$1 [L,R]
RewriteOptions inherit
# AliasMatch ^/~([^/]+)(/(.*))? /home/sites/site7/users/$1/web/$3
# AliasMatch ^/users/([^/]+)(/(.*))? /home/sites/site7/users/$1/web/$3
AliasMatch ^/~([^/]+)(/(.*))? /home/sites/home/users/$1/web/$3
AliasMatch ^/users/([^/]+)(/(.*))? /home/sites/home/users/$1/web/$3
</VirtualHost>

Note that I used the RaQ control panel to create the domain and it
assigned site7.  Here I unceremoniously ignore that and have it refer
to the other domain.  Here is the message I get (I have SSL turned on):

[warn] VirtualHost aa.bb.cc.dd:443 overlaps with VirtualHost 
aa.bb.cc.dd:443, the first has precedence, perhaps you need a 
NameVirtualHost directive

Note that none of the automatically generated Cobalt sites have a
NameVirtualHost directive.  After starting with the above, none of
my websites are accessible, and besides this solution would never
work across multiple machines.

I think #2 is the right approach, or is it not?  If so, has anyone gotten
this to work?
