We've been clearing our caches--often daily--since the '90s????
Why, I don't think I've EVER "cleared out my cache".......* and I don't exactly look forward to TRYING it.....because well.....
All's I know is that when I go to bigcharts (plus other certain websites), it / they helpfully recollect what I've previously searched for......(I take it that the info's been "cached")
And I sure wouldn't want to lose that stored memory by "clearing out my cache"......
You say that I WOULDN'T though (lose lose that stored / cached memory) ?........
