ipad memory

i have an ipad 2 about a year old i almost never use. it just sits except when i have been out of town for work and used it for notes. i browsed some adult sites back in jan or feb and the link still showed in a small square window in safari along with craigslist from more recent. how long does safari hold those if the ipad is almost never used

Forever… unless you clear them.

In settings you may want to clear cookies and data also but this will also clear your username and passwords for some sites.

thanks guys thats what i kept telling my gf that it was before her and she knows i almost never use this, i knew it had to hold it since i never use the darn thing except for pics and craigslist a couple times. guess i can pass this on to her and maybe put this to rest. so much appreciate the help.
