[Zope] Extracting query string parameters from a URL

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. -Asad __________________________________________________ Do you Yahoo!? Yahoo! Tax Center - forms, calculators, tips, more http://taxes.yahoo.com/
