    That page doesn’t exist, or there’s something funny going on.

    The link that I made worked for me and still works for me. (It is a redirect, because of formatting issues.)

    The original link didn’t work for me when I first clicked on it, but does now. If the redirect was made in the meantime that would explain what happened.

    No, the redirect was made a day before my announcement.

    I have added a little more to the Lakatos section.

    Then it might have been that the latest update to instiki (which appears to have fixed the apostrophe problem) happened in between. Or it’s just one of those unexplained mysteries and we’ll have to call on Scooby-Doo to solve it.

    Actually, the first link still doesn't work for me in Chrome, Firefox or Mobile Safari.

    Oh, that’s odd. It works for me with Firefox on a Mac. Doesn’t work with Chrome on a Mac, then I get a page about creating Cauchy/'s mistake. Same for Safari on a Mac.

    I’m verging on classing this as a WebKit bug. When I view the source in Safari then the link is clearly displayed as http://ncatlab.org/nlab/show/Cauchy\'s mistake. However, if I do “Copy Link” and paste the link somewhere then I get http://ncatlab.org/nlab/show/Cauchy/'s%20mistake. Note the forward slash! Firefox, on the other hand, seems to escape the slash when copying as I get http://ncatlab.org/nlab/show/Cauchy%5C%27s%20mistake when I copy the link from Firefox and that’s the correct backslash.

    Hmm, a quick search shows that “ambiguous” is the right term for this. Forward and back slashes are sometimes considered equivalent as regards URLs.

    I’ve added the redirect with the other slash so that the link works.

    Nice, it works for me now.

    Forward and back slashes are sometimes considered equivalent as regards URLs.

    Does this mean that the proper thing for the Forum to do, when presented with a Lab link containing a slash, is to escape it?

    Eeek. Now you’re claiming that it’s a forum bug. Darn. I thought I’d gotten away with blaming WebKit (and thus Not My Problem). I guess this would be the safest route.

    Even if

    Forward and back slashes are sometimes considered equivalent as regards URLs.

    is technically allowed by the standards, it's still poor behaviour on WebKit's part. (But maybe it's useful for compatibility with something Microsoft.)
