Like others have said for ssh I just use the config file I have a simple bash script for managing it. I then combine it with alias and other bash/powershell files inside my projects so I don't have to think to hard. For url I have a html file in my projects that links all the needed urls that typically links with my projects config file. So if I change my configs dev I don't have to worry about updating my html as well. Simple rule of life if you ever do something a second time turn it into a script.
