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 6 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
