Maybe it is enough to return 404 when the request format is HTML?

Since I use MacBook Pro and don't have a mouse with a middle button, I cannot reproduce the problem. Adding issue watchers works fine for me.

Could someone tell me how the middle button works and causes the error?

#6 Updated by Marius BALTEANU 10 months ago

Yes, middle button means Open link in new tab. To reproduce, go to an issue, right click on the Add watchers link and then Open link in a new tab. Technically, instead of an Ajax request you will do a simple get request.

Thanks, I understand. I think this issue is not a big problem, so the fix that simply returns 404 is enough.

I found that this issue also affects the following links.

  • "Watch" link
  • "Search for watchers to add" link on "New issue" page
