[Zope] Extracting query string parameters from a URL

[Asad Habib]

Hello. Does anyone know how to extract query string
parameters from a URL? I am trying to limit access of
a DTML page to users who have a particular user name
and id. Users who try to access this page have to
enter something of the sort:

http://localhost:8080/somepage.html?user_name=someuser+userid=djje

Is there someway to access the values associated with
username and userid in the URL above? Any help would
be greatly appreciated. Thanks.
