Subject Re: [users@httpd] Reverse Proxy for Web Application (or adding it as extension to Apache web server)
Date Sun, 09 Sep 2018 00:13:05 GMT
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.

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.

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

Typically yes.

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
