Re: Reverse Proxy for Web Application (or adding it as extension to Apache web server) (Apache Users)

I put the files for my app that I wanted to be served behind a reverse proxy into Apache's document root instead to have them served that way (is this a good idea? Can Apache start the server as an extension like this?). I've put the PassEnv directive into httpd.conv, once each for the environment variables I have, but I still get an invalid Google Maps API Key error. Did I do it wrong? I'm attaching the httpd.conf file here again. I'm also attaching the vhosts configuration file, so please let me if I have that done correctly (the file itself, I mean).

I've set the environment variables via the Control Panel, by going to Control Panel->System and Security->System and then clicking on "Advanced system settings" on the left-hand side (I'm using Windows 10), which brings up a window where I can set system-wide environment variables. So I need to how and where to use PassEnv so that it'd pass those environment variables into the server application.

No.

> And I need an email address for the server that I know I'll be able to get emails on, but I don't have a host name aside from the one I'm setting up a virtual host for (and that host name doesn't exist outside of being a virtual host).

What does an email address have to do with HTTP servers?

I'm confident only in using the same email address as the one for
this Outlook account.

> I also need to know where to add the ProxyPass directive if I do have to set up a reverse proxy.
You can simply append it to httpd.conf if you don't want to restrict
it to a particular incoming virtual host. If you do, use that context
instead.

> And do I also need the ProxyPassReverse directive along with that?
Typically yes.

> In my C++ source file, I have two environment variables for the API keys that it needs to work correctly; since it's a Google Maps application with a currency conversion form on it, it needs a Google Maps API Key and an Access Key for the currency API. On lines 130 and 133, I use std::getenv() to get the values in the environment variables. So also need to know how to make that work in Apache.

Apache can't pass environment variables to a backend proxied server
and doesn't start your backend server. What do you want Apache to do
here?
