I own a personal website that uses asp scripts to run various parts of it.  One of the things I'd like to do is create themes or "skins" for my website.  But for the love of my I can't seem to figure out cookies and how they work.  I'm extremely new at actually writing asp lines other than includes.  Could someone please help me?

(Also I've found a few tutorials that say you have to use a form, is this necissary? I'd like to have it so my visitors just click and image and it changes the coding.)

Thanks in andvaced for any help you can give me.

Cookies in ASP is pretty simple.

You write to a cookie like this:
Response.Cookies("cookie_name") = "value"

You read a cookie like this:
SomeVariable = Request.Cookies("cookie_name")

You can define a cookie's expiration date like this:
Response.Cookies("cookie_name").Expires = SomeDateVariable

You may also use cookies as arrays, like this:
Response.Cookies("cookie_name")("sub_name") = "value"
or
SomeVariable = Request.Cookies("cookie_name")("sub_name")
