XSQL set-cookie

Question

When I write an XSQL cookie, it won't actually do it until i refresh the login screen, i.e.:
1) Enter username and password into XHTML page
2) Post to auth.xsql
3) auth.xsql reads the username and password and authenticates
4) all user information for that username and password is pulled out of the database
5) attempt at writing cookie fails.
6) when i refresh the page, the cookie then has a value and shows up.
Why is this? And also, is there any way of deleting the cookie, like with a logout button, using XSQL? Maybe like XSQL:delete-cookie ?
Thanks!
Here's the code:
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="/dvd/dvd.xsl"?>
<database connection="dvd" xmlns:xsql="urn:oracle-xsql">
<xsql:query id-attribute="" tag-case="lower" rowset-element="allusers" row-element="userinfo" bind-params="username password">
SELECT *
FROM LKUP_USER
WHERE USERNAME = ? AND PASSWORD = ? /* AND ACCESSLEVEL = 1 */
ORDER BY USER_ID
</xsql:query>
<xsql:set-cookie name="authuser" only-if-unset="no" ignore-empty-value="yes" bind-params="username password">
SELECT USERNAME
FROM LKUP_USER
WHERE USERNAME = ? AND PASSWORD = ? /* AND ACCESSLEVEL = 1 */
</xsql:set-cookie>
<xsql:include-request-params/>
</database>--

This the flat XML result when the page is first loaded:
<?xml version="1.0" ?>
- <!-- <?xml-stylesheet type="text/xsl" href="/dvd/dvd.xsl"?>
-->
- <database>
- <allusers>
- <userinfo>
<user_id>1</user_id>
<firstname>Malik</firstname>
<lastname>Graves-Pryor</lastname>
<username>malik</username>
<password>malik</password>
<email>[email protected]</email>
<accesslevel>0</accesslevel>
</userinfo>
</allusers>
- <request>
- <parameters>
<password>malik</password>
<username>malik</username>
</parameters>
<session />
<cookies />
</request>
</database>and here is what it looks like when I refresh the page, doing nothing else:
<?xml version="1.0" ?>
- <!-- <?xml-stylesheet type="text/xsl" href="/dvd/dvd.xsl"?>
-->
- <database>
- <allusers>
- <userinfo>
<user_id>1</user_id>
<firstname>Malik</firstname>
<lastname>Graves-Pryor</lastname>
<username>malik</username>
<password>malik</password>
<email>[email protected]</email>
<accesslevel>0</accesslevel>
</userinfo>
</allusers>
- <request>
- <parameters>
<password>malik</password>
<username>malik</username>
</parameters>
<session />
- <cookies>
<authuser>malik</authuser>
</cookies>
</request>
</database>As you can see, the cookie "authuser" is written, but only after I refresh the page. Any clues to that, and also how to delete the "authuser" cookie later on using XSQL so that one can log out of the app?
p.s.: Steven, are you going to release an updated "Building Oracle XML Applications" book anytime within the near future, i.e., next 1-3 months?
