How to make github pages url case insensitive?

Website works for
jerrygoyal.github.io/Flash-Clipboard

but not for (404 error):
jerrygoyal.github.io/flash-clipboard
jerrygoyal.github.io/FLASH-clipboard
jerrygoyal.github.io/flaSH-CLIPboard and so on
You get the idea! How can I make the url case-insensitive?

I've never worked on Jekyll and not sure if my project pages are using jekyll or not. I only created an index.html page and put inside the docs folder of the repository.

I'm using a custom domain (www.jerryfactory.com) to map jerrygoyal.github.io

Here's the URL to my Github Organisation site : https://github.com/JerryGoyal/jerrygoyal.github.io

And URL for my Github project site: https://github.com/JerryGoyal/Flash-Clipboard/tree/master/docs

I'm thinking of moving my project site content to my Github Organisation site if it's possible. So if the URL case insensitivity works for only Organisation site it's fine.

It's a responsibility of the webserver that serving the HTML pages that were generated by Jekyll, and in the case of GitHub Pages, they use a *nix-based webserver that is compliant with case-sensitive URLs when locating resources.

The common way to solve this problem is to always make sure your pages in Jekyll are always lower-case, which in turn will generate lower-cased URLs.

This shouldn't really be a problem, unless your users are typing the URLs by themselves... And in that case, if you want to be proactive, you can use the jekyll-redirect-from plugin and create redirect entries of the most common ways you believe users will try to access each page.

For example, having the main URL as
