+This is basically a question of using your proxy or not. You can 
+control the behaviour of your browser in great detail writing a 
+proxy.pac program in Javascript and setting that program as the 
+proxy autoconfiguration URL in your browser.
+
+An example:
+
+kris@jordan01:~> cat /srv/www/htdocs/proxy.pac
+
+function FindProxyForURL(url, host)
+{
+        var proxy_yes = "PROXY jordan01.int.cinetic.de:3128";
+        var proxy_no  = "DIRECT";
+
+        // Redirect all accesses to mlan hosts to the mlan proxy
+        if (dnsDomainIs(host, ".mlan.cinetic.de")) {
+                return proxy_yes;
+        }
+
+        // Everything else is direct
+        return proxy_no;
+}
+
+So here the program checks if the destination is a mlan-Host, and 
+if so, uses the appropriate proxy on jordan for the access, 
+while all other accesses are direct.
+
+You could do a similar thing with .onion accesses with a trivial 
+modification.
