Hi, we are running distinct instances on 80 and 8080 - when you use the 8080 instance - the url is built for /galaxy not :8080/galaxy http://genome.ucsc.edu/cgi-bin/hgTables?GALAXY_URL=http%3A//genome.einstein.......... thus you cannot pass the data back to the correct instance. What/where is the easiest to pass the 8080 information to the browser? Looking at some candidate files: ucsc_proxy.py ucsc_tablebrowser.xml but perhaps there is a better way, best, joe
