I am a new member running an iPad 1 with ios5. My problem occurs in Safari.
Everything is working ok except with some sites the back button takes me to an old page.
For example, if I choose an article from Techmeme and then use the back button to go
Back to Techmeme, it takes me to the previous "edition" with a different article
On top. It is as if I am being taken to an older cached version of the site.
I have checked settings but don't see anything that provides a fix.
