Moodle Enable HTTPS with a proxy or an ELB

 If you are converting Moodle site from HTTP to HTTPS or setting up from the scratch, it will be a bit tricky as I also experienced.

By the way, I'm not going to talk about how to install the SSL certificate here. This is only about the Moodle configurations you have to do after that.

There are two ways you can do this.

1. Enable HTTPS using a proxy or an ELB


Moodle HTTPS with proxy or ELB


If you have this setup, then again we need to change the config.php as below.

//Change the URL to https
$CFG->wwwroot = 'https://my.moodle.site.edu';
//Add the following line
$CFG->sslproxy = true;

If the SSL proxy configuration is not enabled, your browser will keep trying to redirect. 
You should enable this configuration if you have SSL termination from a proxy or a load balancer. I tried this with an AWS ALB (Application Load Balancer). 

If you don't change the config, it will fail to load the styles and Javascript.


2. Enable HTTPS in Apache server

This is if HTTPS is enabled in the Apache server on which Moodle is hosted without a proxy. This way, the SSL certificate will be required to install in the Apache server itself. Or in other words, SSL termination will be handled by the Apache server itself.

If you do this, you have to update the config.php file in the moodle directory with the HTTPS base URL.

//Change the URL to https
$CFG->wwwroot = 'https://my.moodle.site.edu';

Java, how to create a list with a single element

 I wanted to create a Java List with a single element. Yet, I wanted to add more elements later. So, I was looking for a couple of ways to do this. So far there are multiple elegant ways to create a list with a single element with a one-liner. Not so much for a modifiable list though. Here's what I gathered so far. Followings are a few ways of creating a list with strictly a single entry. Can't add more elements. 1. Collections.singletonList() This returns an immutable list that cannot be modified or add more elements. // An immutable list containing only the specified object. List<String> oneEntryList = Collections. singletonList ( "one" ) ; oneEntryList.add( "two" ) ; // throws UnsupportedOperationException 2.  Arrays.asList() This returns a fixed-size list consisting of the number of elements provided as arguments. The number of elements provided would be an array hence the size is fixed to the length of the array. // Returns a fixed-size list List...
