(A.S. I actually kludged up a fix to my problem in the Zope code, but I think it's an interesting question anyway. ) Well, I did bad :( I sent out a mailing to a large membership list asking them to visit my Zope site. The URL was of the form /a/b?id=98723 where the id number is different for each person and opaquely identifies their record in the database. My problem is that I had a typo in the message, and the URL I actually sent was /a/b/id=98723 Now everyone who visits gets a 'Resource not found' error, unsurprisingly, and sadly, since the URLs are all unique, I can't put in a page telling them how to correct it. Is there any concept of an ErrorDocument or something that I could use to trap all these visits? Thanks again -=-=-=-=-=-=-=-= Clarence Gardner Software Engineer NetLojix Communications, Inc.
