/*

I need the rules on cookie storage here.
If I switch to a page in a different directory, I am probably going to lose the cookie
what happens to cookies called form JS files in a different directory

A cookie set in a subdirectory will not overwrite a cookie set in its parent directory but will hide its value.

To override the path value of a cookie you must include 'path=PATH' in the cookie string. 
If you always want to have your cookies visible throughout the site you should hard code path=/ into the setCookie() function.
If cookies are set in different directories with the same name then the one with the longest (most specific) path 
will be returned

I need to do something with set and getcookie so that I can always get it
Maybe I need to set a temp cookie in every document with its path and then use that cookie to find the other cookie.
