Exclude an alias from virtualhost proxypass

Question

I've following virtual host configuration. The desired result is:

1. If someone requests http://test.myserver.com/myapp, apache serves him from /var/www/myapp
2. And if http://test.myserver.com/ is requested, apache redirects it to port 8069.

2nd is working but 1st is not. Can someone help please!

<VirtualHost *:80>
        ServerName test.myserver.com

        Alias /myapp /var/www/myapp
        <Directory /var/www/myapp>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride None
                Order allow,deny
                Allow from all
        </Directory>

        ProxyPass / http://localhost:8069/
        ProxyPassReverse / http://localhost:8069/

</VirtualHost>

Answer 1

This is how I was able to achive the desired outcome. Following is the working configuration where ProxyPassMatch ^/myapp ! did the trick and except the (server-address)/myapp, all the requests are being proxying to the other server which is open-erp running at port 8069:

<VirtualHost *:80>
        ServerName test.myserver.com

        Alias /myapp /var/www/myapp
        <Directory /var/www/myapp>
                Options Indexes FollowSymLinks MultiViews
                AllowOverride None
                Order allow,deny
                Allow from all
        </Directory>

        ProxyPassMatch ^/myapp !
        ProxyPass / http://localhost:8069/
        ProxyPassReverse / http://localhost:8069/


  CustomLog /var/log/apache2/access.log common
  ErrorLog /var/log/apache2/error.log

</VirtualHost>

Answer 2

Instead of using:ProxyPassMatch ^/myapp ! you could have simply added another ProxyPass directive before the one defining /, like this:

ProxyPass /myapp !
ProxyPass / http://localhost:8069/

Since ProxyPass respects precedence (the first match will be processed), it will correctly redirect to the directory instead of proxying.
