I have a Balance One.
On a number of sites when I visit with iPad or iPhone via WiFi & Balance One, I get a old cached version of the site from my previous visit that is slow to load and then I must reload the site.
I have minimal rules with a simple overflow between the two ISPs. I have reversed the overflow order, still the same - so it does not appear to be a cache at the ISP.
Finally, if i disconnect the WiFi and use Wireless LTE to the device, bypassing the Balance One, I get an updated site and no delay.
Is there a cache somewhere in the Balance One that I am missing?
Otherwise, what would be causing this?
