I need to set the RSS Viewer Web Part to a shorter time. I would like to be able to get the Feed to change shortly (maybe every 10 min). This is for a News feed in an Intranet site and the posters would like it to change fast.
I found out that it was a setting in Site Collection Level. The way to change it is
Go to Site Settings
In Site Administration Section click on link RSS
Set the Time To Live(Minutes) filed with required refresh time
