- Microsoft Passport, versions 1.3, 1.4

SYMPTOMS
========

When a user is returned to your site from the Passport Login server, a long
query string may be appended to the address bar of the browser.

CAUSE
=====

The extra query string parameters may be the encoded Passport Ticket and Profile
information as sent by the Passport Login server for the user.

RESOLUTION
==========

As soon as Ticket (the t parameter on the query string) and Profile (the p
parameter on the query string) are received, the Passport Manager object writes
cookies using these values and you can clear the query string by redirecting the
page to itself minus most of the query string.

NOTE: You may have your own custom parameters in the query string; if so, you
must isolate and re-add these parameters.

For more information on how to detect whether the query string contains
Passport-relevant information, and for sample script for cleaning up the query
string, see the following Microsoft Passport Software Development Kit (SDK) Web
site:

  FromNetworkServer
  http://www.passport.com/sdkdocuments/sdk14/reference/scriptreference/ifaces/ipassportmanager/fromnetworkserver.htm

It is strongly recommended that Passport participant sites clean up the query
string in this way to improve both user experience and security.
