[EP-tech] IRStats2: Slow in Chrome?

Hi James,

I cannot remember off hand what caching issues you may need to deal 
with.  First rule is always make sure you reload the webserver after 
making the changes.  Then on any pages you load make sure your hard 
refresh (e.g. Ctrl+Shift+R).  If you have download graphs on 
abstract/summary pages I think you will need to run refresh abstracts.

This definitely fixed the issue for me and I had several independent 
people test this to confirm.

Regards

David Newman
