<!-- Start Instructions -->
|
|
To help mitigate the cross site scripting threat, Microsoft has
|
|
introduced a new cookie attribute entitled 'HttpOnly.' If this flag is
|
|
set, then the browser should not allow client-side script to access the
|
|
cookie. Since the attribute is relatively new, several browsers neglect
|
|
to handle the new attribute properly.
|
|
<p><b>General Goal(s):</b></p>
|
|
The purpose of this lesson is to test whether your browser supports the
|
|
HTTPOnly cookie flag. Note the value of the
|
|
<strong>unique2u</strong>
|
|
cookie. If your browser supports HTTPOnly, and you enable it for a
|
|
cookie, client side code should NOT be able to read OR write to that
|
|
cookie, but the browser can still send its value to the server. Some
|
|
browsers only prevent client side read access, but don't prevent write
|
|
access.
|
|
<br />
|
|
<br />
|
|
With the HTTPOnly attribute turned on, type
|
|
"javascript:alert(document.cookie)" in the browser address bar. Notice
|
|
all cookies are displayed except the unique2u cookie.
