[galaxy-dev] Refreshing side bar

Hi Guys, So i'm looking at having the dataset history item that is currently running to load in text from a txt file, re-reading the txt file every few seconds or so. I have found where it gets displayed in the /templates/root/history_common.mako and have added <%include file="test.txt"/> so that it will read my text file but that obviously just reads it the once and then moves on. So what I need help with is being able to read it from the file multiple times while the tool is executing. Any help would be greatly appreciated.
