Hello
I can help you to create a reverse proxy with your site/server. I do have over 20 years extensive experience with Apache and have created a number of similar setups previously.
If you would like to send through some additional details on your project, including which version of Apache you are running, if you are running a dedicated server or shared hosting, as well as what your desired outcome is related the reverse proxy, I can confirm back with you and complete the project.
Thank you
Darren
