I need to locate a Squid instance as a forward proxy behind Apache 2.4.6. I don't have enough credits to add inline images. But here it is
As Squid3.3 listens on localhost:3128 and works OK with default config, I have this configuration vhost config for Apache:
<VirtualHost example.com:443>
SSLEngine on
[cert file config]
ServerName example.com
DocumentRoot /var/www
ProxyRequests Off
ProxyVia Off
ProxyRemote * http://127.0.0.1:3128
LogLevel debug
ErrorLog /var/log/apache2/tunnel_error.log
CustomLog /var/log/apache2/tunnel_access.log combined
</VirtualHost>
However my proxy requests are not processed through Squid 3.3 anyhow.
I have ran into a lot of articles around the web explaining caching in front of Apache, however, (maybe I missed) I need Apache to be welcoming CONNECT requests and passing to Squid.
Do you have any idea how to do the configuration?

Edit
Trying with proxypass
ProxyRequests Off
ProxyVia Off
ProxyPass http://127.0.0.1:3128/
ProxyPassReverse http://127.0.0.1:3128/
Apache seems to redirect my request to Squid semi-well. Because Squid this time warns me with:
ERROR
The requested URL could not be retrieved
The following error was encountered while trying to retrieve the URL: /
"Invalid URL"
Some aspect of the requested URL is incorrect.
Some possible problems are:
* Missing or incorrect access protocol (should be http:// or similar)
* Missing hostname
* Illegal double-escape in the URL-Path
* Illegal character in hostname; underscores are not allowed.
Your cache administrator is webmaster.
Because it seems like Squid thinks I would like to get http://icanhazip.com as a page from my own server. (Or am I mistaken?)

Edit 2 - The Diagram
Disred solution would be like:
1) Since I couldnot still find a way out. I would like to improve the question as suggested with a diagram.
2) I have noticed while examining the headers that
GET /
Host: yahoo com
which is passed from Apache to Squid should be
GET http:\\yahoo.com
for instance to be able to work this out.
Diagram URL is at top.
