I am making use of the DTM library download which was intially a pain as you could not specify a specific url as it assumes based on the location i.e. //.
DTM now automatically bring the domain host which is great but i have noticed an issue especially when using different staging environments which requrie a certain port number. It would great if DTM can add the port number if available or just allow you to make use of a data element.
In my current situation i always need to override that piece of code so i can work on all my staging.
