title: Why are file extensions case-sensitive on the web but not on localhost?
body: <p>So I was trying to link an image on my website as <code>&lt;img src="cat.png alt="cat"/&gt;</code> and for some reason it wasn't working. I later found out that when uploaded to my server the file was labeled as "cat.PNG" so I inputted that and it fixed. However, when I was testing my site on localhost, it was fine. Why is this? Is this some security issue or is localhost just smarter when it comes to parsing files?</p>
  
  <p>I know this is a weird and random question but I am curious. Thanks.</p>
