Reverse proxy: unwanted URL change - apache

Question

I have a web-service that I would like to expose through the URL foo.com/bar.
However my Apache reverse proxy does not work as intended.
I have created the file 001-default.conf, which contains the following code:
<VirtualHost *:80>
ProxyPreserveHost On
ProxyRequests Off
ProxyPass /bar http://foo.com:8080/bar
ProxyPassReverse /bar foo.com:8080/bar
DocumentRoot /var/www/foo/
ServerName info.foo.com
<Directory /var/www/foo>
Options Indexes FollowSymLinks MultiViews Includes
AllowOverride All
Order allow,deny
allow from all
</Directory>
</VirtualHost>
Right now I receive a 404 error code.
I want to achieve all hits on foo.com/bar to be silently redirected to foo.com:8080/bar, meaning that the user should only see the URL foo.com/bar.
The reverse proxy redirect should also include requests such as foo.com/bar?=foobar.
I did enable proxy_http and proxy:
% sudo a2enmod proxy_http
Considering dependency proxy for proxy_http:
Module proxy already enabled
Module proxy_http already enabled
I hope that there is someone out there that are able to help me with this.
Similar problem that did not solve my problem:
apache reverse proxy changes url Transparent redirect to port 8080

Try and edit the config to:
<VirtualHost *:80>
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPreserveHost On
ProxyRequests Off
ProxyPass /bar http://foo.com:8080 # Note removed /bar
ProxyPassReverse /bar foo.com:8080 # Note removed /bar
DocumentRoot /var/www/foo/
ServerName info.foo.com
<Directory /var/www/foo>
Options Indexes FollowSymLinks MultiViews Includes
AllowOverride All
Order allow,deny
allow from all
</Directory>
</VirtualHost>
You can also try with mod_alias to avoid te /bar/bar issue you might be facing now.
I do not know much about it, see the documentation: http://httpd.apache.org/docs/2.2/mod/mod_alias.html
Try something like adding this to your conf
Alias /bar http://foo.com:8080
Using this you might wan't to remove the proxy.
