[jira] [Commented] (SOLR-12282) JSONResponseWriter should return
Content-Type application/javascript for JSONP requests
[ https://issues.apache.org/jira/browse/SOLR-12282?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16458427#comment-16458427 ]
Jan Høydahl commented on SOLR-12282:
------------------------------------
Hmm, why would we want to keep this supposedly insecure JSONP capability around when solutions for handling pure JSON with CORS are available and mature?

> Key: SOLR-12282
> URL: https://issues.apache.org/jira/browse/SOLR-12282
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Components: Response Writers
> Reporter: Markus Schuch
> Priority: Minor

>
> The JSONResponseWriter handles two purposes:
> * writing JSON responses (wt=json)
> * writing JSONP responses, namely JSON responses wrapped by a JavaScript function (wt=json&json.wrf=myFunction)
> The response writer returns the same Content-Type in both cases. (default: application/json)
> But for JSONP the correct Content-Type would be "application/javascript".
> The response type is configurable, but it is currently not possible to return the correct Content-Type in both cases with one configuration at the same time.
> The attached patch changes the default Content-Type to {{application/javascript; charset=utf-8}} for responses with wrapper functions (JSONP). If param {{content-type}} is configured, this Content-Type will be returned for both JSON and JSONP to ensure backward compatibility.
