> I haven't yet looked at the code involved for suggestions here; I'm speaking
> based on how I think things should work and not work, based on intuitiveness
> and security. In general I feel it is best practice to use '/' leading
> request handler names and not use "qt", but I don't hate it enough when used
> in limited (search-only) circumstances to propose its demise. But if someone
> proposes its deprecation that then I am +1 for that.
> Here is my proposal:
> Solr should error if the parameter "qt" is supplied with a leading '/'.
> (trunk only)
> Solr should only honor "qt" if the target request handler extends
> solr.SearchHandler.
> The new admin UI should only use 'qt' when it has to. For the query screen,
> it could present a little pop-up menu of handlers to choose from, including
> "/select?qt=mycustom" for handlers that aren't named with a leading '/'. This
> choice should be positioned at the top.
> And before I forget, me or someone should investigate if there are any
> similar security problems with the shards.qt parameter. Perhaps shards.qt can
> abide by the same rules outlined above.
> Does anyone foresee any problems with this proposal?
> On a related subject, I think the notion of a default request handler is bad
> - the default="true" thing. Honestly I'm not sure what it does, since I
> noticed Solr trunk redirects '/solr/' to the new admin UI at '/solr/#/'.
> Assuming it doesn't do anything useful anymore, I think it would be clearer
> to use <requestHandler name="/select" class="solr.SearchHandler"> instead of
> what's there now. The delta is to put the leading '/' on this request handler
> name, and remove the "default" attribute.
