[Myexperiment-discuss] Proxy implementation and testing

[Linde, A.E.]

Long time I know but I’m finally getting around to implementing this. I’ve implemented the Don’s suggestion but it is only returning a blank file while testing.

I have a server which, addressed (or curl’ed) with http://localhost:8080/sac/mysac?metadata returns:

=====
@prefix dc:      <http://purl.org/dc/elements/1.1/> .

<http://localhost:8080/sac/mysac>
      dc:creator "Tony" ;
      dc:description "My SAC" .
=====

But using http://localhost:3000/proxy?uri=http://localhost:8080/sac/mysac?metadata returns a blank file, albeit one with the correct mime type (i’m asked by firefox to choose the app to open a file of type ‘text/rdf+n3’). Is there a problem in the send_data code:

    send_data(response.body, :type => response['content-type'],
        :status => "#{response.code} #{response.message}")

*More importantly, is there any way to debug myExperiment while developing? In _javascript_ I can stick alert()s all over the place to see what variables are being delivered. Is there anything I can do inside the proxy_controller.rb code to see what the variables are up to?

Thanks,
Tony.

Since this will inevitably be cross-domain, it needs to be via a proxy server which is part of the myexp code. Does such a function exist at the moment? If (as I assume) not, and I need to direct the skua call via, say, /proxy?url="" does anyone have a pointer to sample (pref copy & paste) code I can use?
