Re: Access HTTP headers from custom request handler

[Giovanni De Stefano]

Hello Hoss,

thank you for your reply.

I have no problems subclassing the SolrDispatchFilter...but where shall I
configure it? :-)

I cannot find any doc/wiki explaining how to configure a custom dispatch
filter.

I believe it should be in solrconfig.xml

requestDispatcher ... ... /requestDispatcher

Any idea? Is there a schema for solrconfig.xml? It would make my life
easier... ;-)

Thanks,
Giovanni

 SolrDispatchFilter is designed to be subclassed to make this easy by
 overriding the execute method...

  protected void execute( HttpServletRequest req, SolrRequestHandler
 handler,
  SolrQueryRequest sreq, SolrQueryResponse rsp) {
sreq.getContext().put( HttpServletRequest, req );
super.execute( req, handler, sreq, rsp )

nope.
you must edit the web.xml and register the filter there

Right, you will have to build a new war with your own subclass of  
SolrDispatchFilter *rather* then using the packaged one.

Access HTTP headers from custom request handler

[Giovanni De Stefano]

Hello all,

we are writing a custom request handler and we need to implement some
business logic according to some HTTP headers.

I see there is no easy way to access HTTP headers from the request handler.

Moreover it seems to me that the HTTPServletness is lost way before the
custom request handler comes in the game.

Is there any way to access HTTP headers from within the request handler?

Thanks,
Giovanni
