Describe the Bug

Following the documentation for adding RSS to my site, I tried to add the pretty-feeds-v3.xsl stylesheet to the site so that users going to the rss.xml URL would see something introducing them to what RSS is.

However, the styling never seems to work. I get the same browser output with or without the stylesheet specified. I checked the returned headers with wget:

 wget localhost:3000/rss.xml
--2022-07-21 21:54:25--  http://localhost:3000/rss.xml
Resolving localhost (localhost)... 127.0.0.1, ::1
Connecting to localhost (localhost)|127.0.0.1|:3000... connected.
HTTP request sent, awaiting response...
  HTTP/1.1 200 OK
  Access-Control-Allow-Origin: *
  Content-Type: application/xml;charset=utf-8

  Connection: keep-alive
  Keep-Alive: timeout=5
  Transfer-Encoding: chunked
Length: unspecified [application/xml]
Saving to: ‘rss.xml’ 

I'm not sure if it's the cause of the issue, but there is one header missing. The documentation for pretty-feeds-v3 says that in order to use the stylesheet you have to set the header x-content-type-options: nosniff, but Astro doesn't seem to be doing that.

Sorry, I think this doesn't work on stackblitz but it works fine locally.

Thanks for the issue @garfieldnate! If the output is a static .xml file, we don't have a way to set your headers. This has to be done however your specific host supports it.

If I misunderstood and this is an issue with our server output using an adapter, please let me know.

This issue is quite state and we didn't get a response, so closing. Please reopen if you are still having an issue in 1.0.
