How to create conditional ProxyPass?

Question

I have the following config for one of the sites-available .conf file.
Its configure to load the ghost blog if you hit blog.example.com.
Somehow its causing example.com to serve up the blog as well. But thats fine too.

<Virtualhost *:80>
  ServerName blog.example.com
  ServerAdmin admin80@example.com
  ProxyPass        /  http://localhost:2368/
  ProxyPassReverse /  http://localhost:2368/
</Virtualhost>

So I just installed phpmyadmin and I realized I can't access it with http://example.com/phpmyadmin. Accessing that page will bring up ghost's 404 page not found instead.

So I guess I need some conditional ProxyPass to ignore /phpmyadmin ?
I tried the following by it doesn't work too.

<Virtualhost *:80>
  ServerName blog.example.com
  ServerAdmin admin80@example.com
  ProxyPass        /phpmyadmin  http://localhost/phpmyadmin
  ProxyPassReverse /phpmyadmin  http://localhost/phpmyadmin
  ProxyPass        /  http://localhost:2368/
  ProxyPassReverse /  http://localhost:2368/
</Virtualhost>

Apache just hang and I have to restart it when I hit http://example.com/phpmyadmin.

Update:

I tried the following, and it loads up phpmyadmin login page. Just added :80 after localhost. and give a specific domain name for the virtual host instead of *.

<Virtualhost blog.example.com:80>
  ServerName blog.example.com
  ServerAdmin admin@example.com
  ProxyPass        /phpmyadmin  http://localhost:80/phpmyadmin
  ProxyPassReverse /phpmyadmin  http://localhost:80/phpmyadmin
  ProxyPass        /  http://localhost:2368/
  ProxyPassReverse /  http://localhost:2368/
</Virtualhost>

Problem now is, it redirects to http://localhost/phpmyadmin/index.php?token=8fa78a71a166399749b58cd3cb66b7f2 instead. Probably some configuration with phpmyadmin I guess.

the proxy thing works now. but redirection after login seems to be wrong. — resting, Sep 01 '14 at 10:05
Note: Don't forget to set `ProxyRequests Off` to prevent the public use of your server as a proxy server. — Gerald Schneider, Sep 01 '14 at 10:14
@GeraldSchneider Cool. I'm not aware of that. So do I just include it before the closing `` tag? — resting, Sep 01 '14 at 10:26
I usually have it near the start of the VirtualHost directive, but I don't really think it matters. — Gerald Schneider, Sep 01 '14 at 10:27

You can use the ! target to prevent a location to be proxied:

<Virtualhost *:80>
  DocumentRoot     /path/to/parent/of/phpmyadmin
  ProxyPass        /phpmyadmin !
  ProxyPass        /  http://localhost:2368/
  ProxyPassReverse /  http://localhost:2368/
</Virtualhost>

This will proxy all requests to localhost:2368, except those to phpmyadmin.

Of course you'll have to set a document root, otherwise phpmyadmin won't be found.

Cool. This is the easiest solution and it solved the redirection to localhost after logging in to `phpmyadmin` too. So the redirection was caused by the proxy thing instead of some configuration. – resting Sep 01 '14 at 10:24
