The above matches any URL having "/wordpress" immediately after the hostname

The above sends anything not starting with /wordpress to the Ubuntu machine.

The above sends the URLs starting with /wordpress to the Wordpress server, but 
only those URLs.

What do you mean by "without rewrite or redirect"?

If you want a URL which does not contain "wordpress" to be served by a server 
which only has content under the directory "wordpress", then you *have* to 
have a rewrite somewhere along the way.

I would suggest creating two ACLs:

acl wordpress urlpath_regex ^/wordpress
acl notroot urlpath_regex ^/..*

That second URL will match any URL with one or more characters after the / 
following the hostname (in other words, the *only* URLs it *won't* match are 
either the hostname itself, or the hostname plus a / and then nothing 
further).

Then you can use these to direct requests for /wordpress to the Wordpress 
server, anything else except the 'null' URL to the Ubuntu server, and the null 
entries to Wordpress (but you'll still have to have a redirect on the 
Wordpress machine so that http://server ends up serving content from 
http://server/wordpress):

cache_peer 192.168.1.150 parent 80 0 no-query originserver name=ubuntu
cache_peer_access ubuntu deny wordpress
cache_peer_access ubuntu allow notroot

cache_peer 192.168.1.153 parent 80 0 no-query originserver name=diskstation
cache_peer_access diskstation allow wordpress
cache_peer_access diskstation deny notroot
cache_peer_access diskstation allow all
