[Zope] Finding unique objects in a ZCatalog returned list

[Mike Groves]

Thanks for the suggestion Oleg,

Would the rid be unique in this case? Would this be a better key to use?

All the objects returned are my own ZClasses so alternatively I could add a
property which I could make sure is unique for all items.

Any thoughts anyone?

Thanks

Mike

   Oops, forgot to say, that even this does not guarantee uniquness.
Consider these URLs:
   http://my.server/Folder
   http://my.server/Folder/
   http://my.server/Folder/index_html
3 different URLs point to the same object.
