Limit Your Cookie Size

There are a number of important limitations on the use of cookies by Web site developers. This is because cookies are intended to be used only for infrequent storage of small amounts of data on the user’s machine. Although how much cookie information is stored and for how long is up to the browser makers, the following limits generally apply:

300 Cookies total
20Cookies per server (not per page or site)
4K of dataPer cookie (both the name and value of the cookie count towards this limit)

As a result, it’s not a good idea to create separate cookies for each value you’d like to save. Instead, combine those values into a single cookie separated by a known delimiter.
