Django cookie，我怎么设置它们?

I have a web site which shows different content based on a location the visitor chooses. e.g: User enters in 55812 as the zip. I know what city and area lat/long. that is and give them their content pertinent to that area. My question is how can I store this in a cookie so that when they return they are not required to always enter their zip code?I have a web site which shows different content
