Cannot retreive cookies

Hi,

when I write a cookie by processing a local HTML file ("Write cookie"), which I atferwards can display by another HTML file ("Read cookie"), I CANNOT retreive the same cookie by scraping "Write cookie". Why?

best regards

Read cookie ====

document.write(document.cookie);

Script run after/ before scraping "Write cookie" ===

cookies = session.getCookies();

// Loop through Cookies
if (cookies.length == 0){
session.logError("No cookies");
}
for (i = 0; i < cookies.length; i++) {
cookie = cookies[i];

// Write Cookie information to the Log
session.logError( "COOKIE #" + i );
session.logError( "Name: " + cookie.getName() );
session.logError( "Value: " + cookie.getValue() );
session.logError( "Path: " + cookie.getPath() );
session.logError( "Domain: " + cookie.getDomain() );
// Only log expiration if it is set
if (cookie.getExpiryDate() != null) {
session.logError( "Expiration: " + cookie.getExpiryDate().toString() );
}
}
