Can someone add 2009 to the tile?

Given that this article is 6 years old, and the upcoming vNext is being touted as practically a rewritten v1.0 product... will this constraint still hold for the new ASP.NET coming next year?

Original author here!

Microsoft fixed this awhile ago; the constraint definitely is dead in vNext. You do, however, still need to set a flag explicitly to disable the behavior described in this post. http://haacked.com/archive/2010/04/29/allowing-reserved-file... has instructions on how this worked in ASP.NET 4, and I believe the situation is similar in 5.

Also, just to get this out of the way since it comes up every time this is posted, my description of CP/M is slightly incorrect; it turns out to have had a much saner COM/LPT/etc. situation than DOS had. The rest of the article was however correct.

Why not edit both of those points into your post? It must be easier than chiming in on the comments section every time it's posted.

Why submit a 6 year old tech article? What's the context and relevance?

HackerNews isn't a current affairs site, or at least not only one. Interesting articles, whatever the age, are totally valid.

I know, I've been here three years now. I just assumed there was additional context for this article.

For classic asp you can avoid this when accessing files via the command line by using a extended file path format:

notepad \\?\c:\inetpub\wwwroot\com1.asp

http://localhost/com1.asp

This also has the hilarious result that "normal" windows tools can't delete the file without using the extended path.

Actually, it's easily fixable with:

relaxedUrlToFileSystemMapping="true"

(google that). It was fixable many years ago, and I have no any idea why today it is on hacker news, lol

You're completely right that this got fixed in ASP.NET 4, but I still think it's a fun read to see how an unyielding tribute to backwards compatibility can have really odd implications.

There was a system BSOD in IE, where you made an iframe that included these reserved names, crashed the OS.
