[jira] [Commented] (SOLR-3346) qt Dispatching Request Handler
[ https://issues.apache.org/jira/browse/SOLR-3346?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13278434#comment-13278434 ]
Hoss Man commented on SOLR-3346:
--------------------------------
bq. Credit: Hoss's idea
to be clear, i did not suggest that we should eliminate qt support from SolrDispatchFilter.
what i said in SOLR-3161 was...
{quote}
change the example solrocnfig to use handleSelect="false"
...
Bonus points: someone can write a DispatchingRequestHandler that can optionally be configured with some name (such as "/select") and does nothing put look for a "qt" param and forward to the handler with that name – but it can have configuration options indicating which names are permitted (and any other names would be rejected)
{quote}
my entire point was that we should leave in support for 'handleSelect="true"' exactly as it is for the multitudes of existing users who are happy using "qt" w/o any security concerns, but that we could _also_ offer an optional DispatchingRequestHandler for people who want param based dispatching but want to limit it to only certain handlers

> Instead of 'qt' being handled by the SolrDispatchFilter (a Servlet Filter), it would be better implemented as a request handler, with a suggested name of DispatchingRequestHandler. This is better because:
> * it keeps the servlet filter more focused / simplified (albeit just a little)
> * it simplifies solrconfig.xml by removing/deprecating handleSelect="true". 'qt' is less magic, it works more explicitly.
> * if you don't want to use 'qt' dispatch, simply don't use DispatchingRequestHandler
> * DispatchingRequestHandler would get used by EmbeddedSolrServer but SolrDispatchFilter is not.
