Subject: RE: Possible file download bug?

Message-ID: <VI1P192MB03520FE42EE0AD08FFCF9216C8EF0@VI1P192MB0352.EURP192.PROD.OUTLOOK.COM> (raw)

A 200 with an HTML page indicating, something like 'this server does not exist - did you mean to type one of these options'?

The first time I hit this, some errant code was trying to reach a website using http://ftp.<website...>  The author was trying to run through 'try http, if failed try ftp' but had messed up a little.  Problem is that the file appeared to download correctly but just contained the HTML error page.

My local ISP 'catches' page load errors and returns their own generated HTML error page and the bug I'm seeing results from a file download believing it succeeded when actually it downloaded just a dummy HTML page.

I don't know whether you can do the same or whether the files you are downloaded are more diverse and need more careful checking, perhaps outside of the file download function.

When the file is not found for download, does the ISP forward a 4xx or 5xx error code, or a 200 as though nothing went wrong?
