The 36-year-old French goalkeeper has put-pen-to-paper on a new deal that ties him to the club until June 2011.
"I'm delighted to be staying here for another year, it's a privilege to be part of what this Club is trying to build," he told the official Dons website.
"The progress the Club has been making over the last few years has been unbelievable, every day you feel it growing and growing and I hope to be part of it for a long time.
"I still feel like I have a lot to offer, I'm as fit as I've ever been and I've worked hard to stay the best shape I possibly can."
