I have some URL entries in my bibliography. In several of them, I noticed that a break after "http://" instead of after "http" would improve both layout and readability. This is how one entry looks like right now: 
How can I enforce a break after "http://" instead? Or, is ist possible to remove the "http://" altogether (only have it in the link?)
This is how the URL is provided:
howpublished = {\url{http://www.harrisgeospatial.com/ProductsandSolutions/GeospatialProducts/ENVI.aspx}},
