I’m not sure if it’s a bug as such. It’s related to me having a LOT of cookies causing large headers. IIS works straight out of the box (It was a while ago when I first set the site up but I think it worked on HTTPS but not HTTP). I’d tried with help of others to change Lucee settings to make it work, but could not get it working. There is a lengthy ticket about this
Happy to post it as an issue to be looked at, where would I do that?
