Hallo Dieter,
As I supposed there did not exist a clean solution (I don't like extrenal python methods -- Sorry Andy!) for that problem. It's even not in builtin in Zope :-( ??? What does that mean "not builtin in Zope"? I did not see a Zope version without the External Method product. Oh, sorry this is a misunderstanding caused by my english! I meant the possibility to get a manipulated query string to use them in <a href=""> tags out of the box. So I meant the method (or something similar) I programed in the hotfix product.
So I programmed my first hotfix product which adds the method 'query_string' to the HTTPRequest class. While you do not like External Methods, I do not like "Hotfix" products. But that is personal taste... Ok, a hotfix manipulates the innards of a stable system which external methods do not...
