SOLVED: How to configure Apache2 with Reverse Proxy. Map an internal website to a folder of another (public) website on the same server - apache

Question

I have build a SPA and deployed it to my server. It is running on http://my-server:3000.
I then installed Apache2 and created a static page. This website is on the same server http://my-server:80 and is open to the Internet via a My-domain.
What I'm trying to accomplish now is to add a link on this static page (http://my-server/foo) which is redirected to http://my-server:3000 in such a way that the here deployed SPA can be run from this sub-folder.
I configured a new Virtual host in Apache2 with the following configuration:
<VirtualHost *:80>
ServerAdmin webmaster#localhost
ServerName My-domain
ProxyRequests Off
ProxyHTMLEnable On
ProxyHTMLExtended Off
ProxyPreserveHost On
ProxyPass /foo/ http://my-server:3000/
<Location /foo/>
ProxyHTMLURLMap / /foo/
ProxyPassReverse http://my-server:3000/
SetOutputFilter INFLATE;DEFLATE
</Location>
<Proxy *>
Order allow,deny
Allow from all
</Proxy>
LogLevel info
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
Although the SPA is accessed and all the files are loaded the application will not start due to the error No match for URL in routes. I think it is due to the fact that the SPA is build to run in the root of a website and I'm now trying to run it in a sub-folder.
Does anyone know if this is possible? A solution would be appreciated much :-)
I found a solution which works for me :-)
Since I can use any prefix before My-domain like foo.My-domain, just found out recently, I changed the configuration for my Virtual host to this:
<VirtualHost *:80>
ServerAdmin webmaster#localhost
ServerName foo.My-domain
ProxyRequests Off
ProxyHTMLEnable On
ProxyHTMLExtended Off
ProxyPreserveHost On
ProxyPass / http://my-server:3000/
<Location />
ProxyPassReverse http://my-server:3000/
SetOutputFilter INFLATE;DEFLATE
</Location>
<Proxy *>
Order allow,deny
Allow from all
</Proxy>
LogLevel info
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
And because my SPA now is allowed to run in the root of a website it is working. :-)
