Here's my contribution: http://www.drdobbs.com/web-development/restful-web-services-a-tutorial/240169069.  It seems to go into sufficient detail to provide a satisfactory answer to your question.

Which apparently broke the URL. Here is the link to the comment:

Is this pattern RESTful? Or something else?

Clue: What's that semicolon doing there?

  • copying the link location appends %E2%80%8C%E2%80%8B to it for some reason. looks like percent encoded UTF8 Commented Feb 23, 2015 at 17:14

    Yeah, but copy/pasted from where? Commented Feb 23, 2015 at 17:43
  • Zero width Unicode characters such as the ZWNJ or ZWJ can be used to append a mostly invisible tracking ID onto an URL. It's a bit of a dark pattern. Proper use of percent-encoding can mitigate any such problems.

This is hitting an edge case with the markdown space forcer workaround. In order to remove it we have to rework the comment structure from tables to something nicer. I'm deferring this one for now.

    I think you probably meant to link to this MSE post instead of that one. But see also this answer; there are other ways to fix this problem. (In fact, I just realized that adding word-wrap: break-word to that CSS fix makes it work even better; I'll add that to the next SOUP release.) Commented Mar 2, 2015 at 16:41
