Play! 2 Framework doesn't recognize Apache port forwarding - apache

I've just finished developing my first Play! 2 application and have to deploy it to my school server. The application runs on port :9002 and we use port forwarding in order to have a nicer URL (e.g. "some.server.com/MyPlayApp/" instead of "some.server.com:9002/").
I'm starting Play! on the server by using "start 9002" and everything is working fine. The only problem is that Play! doesn't seem to know about the port forwarding and all my assets (all CSS, JS etc) cannot get loaded. They should be loaded from "some.server.com/MyPlayApp/assets/stylesheets/main.css", but what Play! tries to do is load them from "some.server.com/assets/stylesheets/main.css". And of course all other in-app URLs are crashing because they're trying to access "some.server.com/section" instead of "some.server.com/MyPlayApp/section".
I tried specifying a baseUrl in the config file, I tried adding an .htaccess file on the server with RewriteEngine On and RewriteBase /MyPlayApp/, I tried modifying the route for the assets and a few other "tricks" to no avail. I have a dirty hack in mind but I would really like to do this the Play! way if possible.
Thanks for any help or suggestions!

Mod wsgi and apache configuration

I'm facing the following issue: i've a public web server running on a given URL, say, www.mysite.com.
It uses apache2.
I've developed a python web app and I want to make it publicly accessible.
Locally, I use the command
mod_wsgi-express start-server wsgi.py
to start the server and everything works.
However, I would like to link only a specific URL to my app, such as mysite/my_test, leaving apache2 serving all the other requests.
In other words, I would like to set the server URL for mod_wsgi-express to mysite/my_test port 80.
By default I get Server URL: http://localhost:8000, and I would like to change this.
I've tried the --mount-point option, but I didn't see any difference.
I know I can change the apache configuration and adding WSGIScriptAlias but I'm facing multiple issues, so I'm searching for a quickest and easiest way.
Hope this is clear.
Thanks.

Apache Admin/Manager page lost after adding Virtual Hosts

I wanted to host a couple of websites (and apps) on the same VPS, so my idea was to have it like this:
Site 1
- HTML content only
Site 2
- PHP and HTML content
Site 3
- Java / SpringBoot app
Site 4
- Python app
Site 5
- Java / SpringBoot app
So I got the smallest pack on DigitalOcean, and thought I would start with Apache. Note: I configured the OS already, and tested basic functionality (see more info below)
I installed Apache, configured it to work with my domain (an actual one, not from hosts) and it loaded the basic HTML page. Before I did this, I tested my-domain.com:8080 and it showed the Apache Admin page, all fine. Unfortunately, now after adding my first VirtualHost (and deleting the default one), my Admin page is not accessible anymore (getting a timeout). I also used Let's Encrypt to test how SSL works.
The current state of sites-enabled:
000-default: NOT ENABLED, doesn't work even if enabled
my-domain.com: ENABLED, working with SSL, redirects to SSL by default
my-domain2-from-hosts-file.com: ENABLED, not working, redirects to the default domain
Ideally, I'd like to have a different VirtualHost/domain for each WAR deployed, but let's get the admin/manager page working first.
What could I be doing wrong? I can post logs and config if needed.
Turns out firewall was the one to blame. Port 8080 became blocked after I added Let's Encrypt SSL using their script, so... that's weird.

Correct Apache Configuration And Htaccess

I've just reset my Ubuntu 14.04 LAMP server hosted with digital ocean. Could someone tell me the 'proper' way to do server configuration. My goal is to do everything as clean as possible (and hopefully well structured).
I intend on using the server mainly for programming and data analytics, however I do plan on hosting my website in /var/www/html. I also plan on using letsencrypt/certbot to get an easy SSL. With this in mind, these are the main goals I would like to accomplish:
1) Redirect the website to ALWAYS be served through https AND www.
2) Enable HSTS for the entire website.
3) Enable clean url's (remove .php extensions and what not).
Since I would like all of these properties to be used across the entire website, should the configuration be done inside of the /etc/apache2/ folder? Or should it be done inside of .htaccess?
And if it should be done inside of apache2 configuration, which file should I add it to? And finally, how exactly should it be added? (for example vhost 80/443, inside of a mod_something section, etc).
Thank you in advance, I would appreciate and consider any advice about Apache and htaccess!

Apache routing without htaccess

I am working with a custom website built in PHP running on Apache server. The client wants to move it to a new server. I moved everything including the .htaccess file, the homepage loads fine but all the other urls like site.com/register isn't working. I'm sure this is not handled by code in the old server because I renamed everything (including .htaccess) and it still works. If I create a file like test.php in the old server, I can access it like site.com/test. It doesn't even hit the index.php file. Also, not all the urls work like this, some are loading through files in other folders.
So my question is - what are the possible ways that Apache can let user access site.com/test without the .php extension. It must not be using .htaccess. Also, we should be able to add exceptions to this so that some urls can be loaded differently.
you can achieve same thing in hosts file if you are using Linux server. you need to define same rules in hosts configuration file.

Configuring Mass Virtual Hosting + SSL on development machine

Is there a way to use this, or something like it, for SSL enabled hosts?
VirtualDocumentRoot /www/vhosts/%0/public
I want to avoid having to configure Apache every time I start working with a new domain on my development box. It would be nice to just add a directory, follow standard naming conventions, and be able to automatically access the site with HTTP or HTTPS.
I realize this definitely isn't the route to go for a production server, but it should be ok just for development.
One example came pretty close using mod_rewrite, but it still requires updating a configuration mapping file when you add a host (which I'm trying to avoid).

Any ideas?
Thanks
The author of the article I referenced above was nice enough to come up with a solution.
This is working on Apache 2.2:
RewriteRule ^/(.*)$ /var/www/%{HTTP_HOST}/htdocs/$1 [E=VHOST:${lowercase:%{HTTP_HOST}}]
