When you submit that form, it’s going to go to the URL `/submit`. Say you need another submit button that submits to a different URL. It doesn’t matter why. There is always a reason for things. The web is a big place and all that.
I web searched around for other ways people have tried handling this.
One way was to give up on submitting to different URL’s, but give each submit button a shared name but different value, then check for that value when processing in order to do different things.
