You add also the search criteria to your URL?
I.e. you use


If you simply append "?sort_on=theme" to


Then, you would have two '?parameter' sections. Only the last
would be taken. The first would be part of the path which should
give you a NotFound Exception. But maybe, there is a bug somewhere.

You could also use a <dtml-call "REQUEST.set('sort_on','theme')">
in "your_method" before the "dtml-in", in case the sort order
is fixed.

That is a good approach. If the same parameter is repeated,
Zope will bind a list of all values to the parameter name.

If you would like to be sure to get a list (or no value at all),
you can use "theme:list". This will ensure, that a list is
bound even if there is only a single "theme" parameter.

This is irrelevant for your application, however.

Usually, the browser builds such URL for you (out of a form).
E.g., if you use a multiple select box or several check boxes
with the same name, the browser will construct corresponding
"param=v" for each selected/checked value.

HTTP 1.1 (and I think HTTP 1.0) has removed the length restriction.
At least Zope/Zserver will not impose an unreasonalble limit.

Someone else suggested to use a post (rather than get) request.
In general, I would warn you against this solution.
It will break the "dtml-in" batch support.
