Java Plug-in supports all cookie policies that are supported in both Internet Explorer and Netscape Navigator browsers. Cookie policy can be configured in both browsers (see your browser guide for details). There are various options, including the following:
Always accept cookies
Disable all cookie use
Prompt/Warn before accepting a cookie
Only accept cookies from a server if they get sent back to that server
When cookie policy is changed in the browser, it will take effect the next time an HTTP/HTTPS connection is made via Java Plug-in.
Java Plug-in does not provide cookie-caching support. Instead, it consults the browser every time an HTTP/HTTPS connection is made. Thus the browser is the only place where cookies are stored. Any change to a cookie in the browser is reflected immediately in Java Plug-in when a new HTTP/HTTPS connection is made.
