Use of Cookies in Client Program
JavaScript string object document.cookie holds cookies that are valid for this document and can be used to either set or retrieve cookie values
In WebWisdom example, we have pages with a form that sets values of parameters common to several foils and stores for a certain length of time. This is entirely processed client-side with JavaScript interpreting form and storing values in appropriate cookie entries
These cookies are read on other pages (consistent with PATH and DOMAIN) and if present used to define JavaScript variables that are used in "parameterized HTML”
Note document.cookie is set to a single cookie value but when read gives all cookies for this document!
