Fix S3 Content Type

This extension solves a known issue with some S3 buckets (such as Cubbit) where HTML files are served with incorrect headers (Content-Type: application/octet-stream or Content-Disposition: attachment), forcing the browser to download the file instead of displaying it as a web page.

What it does: Automatically intercepts requests to *.s3.cubbit.eu domains and corrects the HTTP response headers “on the fly”:

1. Sets Content-Type: text/html for .html files.

2. Removes Content-Disposition to prevent forced downloads.

Result: Web pages hosted on your S3 bucket will once again be visible and navigable directly in the browser, without the need for complex server-side or proxy configurations.
