Are the downloads the old, compiled code? The iexplore.exe in IE 1.5 says modified in 1996. And it runs on my Windows in 2019. That's a feat!

(Can't find any pages to open, though, guess it's too old http and possible tls stuff in the way?) Edit: Found some urls that worked

View on HN

http://example.com should work, it doesn't force https

Can't get it to work. But http://matsemann.com works. I think the difference is that my domain works even without a "Host" header.

Edit: Not quite correct that it works. My domain responds with a different dummy-page in IE 1.5. I get the same dummy-page with curl

  curl http://matsemann.com -i --http1.0 -v -H 'Host:'

Difference being it's served as 200, while same command for example.com with no host gives 404.

I think the web is just broken without host headers, as too much is running on the same ips / through routers before touching the real underlying page.

Host headers are explicitly required by the spec, and there are no clients left that leave them out (including non-browser clients like curl and wget). There is simply no reason to facilitate requests that have no Host header, so servers receiving them quite rightly serve some kind of error response.

Required by the HTTP 1.1 spec, not the HTTP 1.0 spec

Or http://neverssl.com

Yeah they should be; both Microsoft and Intel have a big reputation when it comes to backwards compatibility in their operating systems and instruction sets. It's only been fairly recently that they're starting to break with that, notably with Edge. Not sure about Windows yet, but, wouldn't be surprised if eventually they just put an older windows VM in there - if they haven't already.

Nah, you can't run 16-bit executables or NE executables in modern 64-bit Windows any more. The virtual 8086 mode that was being used is basically unavailable in long mode.

It should be noted that AMD designed the 64-bit extensions not Intel. One of the rare cases Intel had to accept third party instructions.
