ProxyPass within plesk 10/11

Question

I would like to redirect some folder within apache2.

My webserver uses with plesk 11.

I followed this tutorial. It says I've got to put redirection rules in this file /etc/apache2/sites-available/default. For my webserver this file doesn't even exist. I guess that's because of plesk's website management. However there is only this one file: 000-default. I did not modify it!

I also managed to locate the config file for my domain. Which is located here

/var/www/vhosts/example.org/conf/last_httpd.include

I want to solve my problem with Apache 2 "ProxyPass". Because I think that's the easiest way to solve the redirect.

As I found out, I have to add this line

ProxyPass /folder/map/ http://www.google.de

This does not work. It exits with error "403 forbidden". Please give me a hint. Thank you!

Plesk 10/11

1. Create your individual config for apache2:

   cd /var/www/vhosts/example.org
   sudo touch conf/vhost.conf
   sudo vim
   

2. Insert your directives there

3. Press I and insert these lines:

   RewriteEngine On
   ProxyPass /directory/subdir/ http://localhost:8123/
   ProxyPassReverse /directory/subdir/ http://localhost:8123/
   

4. Press Esc, followed by :,write: wq and press ↵

5. Tell Apache to use the config. In a terminal:

   sudo /usr/local/psa/admin/bin/httpdmng --reconfigure-all
   sudo service apache2 restart

Plesk 12

Answer 2

The other answer is correct, but I have something to add:

ProxyPass /directory/subdir/ http://localhost:8123/
ProxyPassReverse /directory/subdir/ http://localhost:8123/

There is no need to add RewriteEngine On here.

Then from a terminal, run:

/usr/local/psa/admin/bin/httpdmng --reconfigure-domain <YOUR_DOMAIN>

There is no need to restart httpd.

Answer 3

This is right:

ProxyPass /directory/subdir/ http://localhost:8123/
ProxyPassReverse /directory/subdir/ http://localhost:8123/

But I had to activate the proxy_http module first, either using the checkbox in Plesk (Tools & Settings > General Settings > Apache Web Server) or in a terminal:

sudo a2enmod proxy_http
service apache2 reload

Otherwise you'll get errors like this in your log:

No protocol handler was valid for the URL /myapp. 
If you are using a DSO version of mod_proxy, make sure the proxy submodules are included in the configuration using LoadModule.
