Serve files as text in OpenHTTPd

Extra: Adding more file extensions

$ curl -I https://ptrace.org/logtest.log
HTTP/1.1 200 OK
Connection: keep-alive
Content-Length: 12546607
Content-Type: application/octet-stream

The “utf-8” charset is an extension to the default “us-ascii” charset and therefore compatible.

Without “log” being added to the list of text/plain files, it would not be known to httpd. And unknown files, are being sent with Content-Type “application/octet-stream”, which browsers cannot display and therefore download.

This is a text file, but the browser would instantly download it, instead if displaying it:

$ curl -I https://ptrace.org/unknown.foo
HTTP/1.1 200 OK
Connection: keep-alive
Content-Length: 30
