can u do this?<BR>or how can u get around this<BR><BR>spanxI had this same problem, and found a suitable workaround. None of my strings had commas in them, so I turned my array into a comma deliminated string.<BR><BR>For example, if my array had the values ("CWRU", "OSU", "UF") I would store the following string in my cookie: "CWRU,OSU,UF".<BR><BR>Then, when you need the array out of the cookie, just do a Request.Cookies[ "key_value" ].Value.Split( ",".ToCharArray() ). This will give you your array that you would've stored in the cookie!<BR><BR>(As a side note, if your array values could contain commas, make sure to use a different deliminator, such as ~, |, &, etc.)
