http:// is appended to attribute URLs.
2013/2014 Geospatial Portal will append http:// to any attribute field that is defined as hypertext through the GeoMedia Database utilities.
To work around this issue either:
1. Do not include the http:// in the data, only store the URL,
2. Do not define the field as Hypertext through data base utilities and store the data or create a view where the data is true html.
