RE: modify non-persistent cookies

In IIS, you can disable the ASP session state so that the session cookie id is masked
(http://support.microsoft.com/default.aspx?scid=kb;en-us;Q244465).

If you want to further mask any session cookie on an IIS box, try ServerMask (www.servermask.com).

Best,
Chris

Hi,

Using application assessment proxy tools like Achilles, WebProxy or Odysseus you can intercept in and outbound headers and data.

You can therefore either modify the cookie on the way in (so your version of the cookie is held by the browser); or the way out (substituting your data for the cookie).

Regards,
G.
