It's worth noting that the file extension doesn't hold much significance in the realm of HTTP.
In the world of HTTP, there is no direct correlation between "files" and requests/responses; it's all about content and headers. As long as the response header specifies the type of content being sent back, the specific URL or file extension used for the request becomes irrelevant.
For example, the URL could take many forms:
- /style.css
- /script.js
- /data.txt
- /api/endpoint?query=example
- /random/resource
- and so on...
Ultimately, what matters most is the actual content and metadata attached to the response, not the name or extension of the requested resource.
