connect-jsonp - Simple jsonp response decorator for connect

•    Javascript

In order to facilitate caching as well as avoid downstream middleware conflicts the filter config option exists and instructs this module to filter (or not) the callback param from the request url. This defaults to false but can be specified passing either a boolean or the literal {filter: true} to your requires statement. In is important to note that you will want to filter the callback param if you are planning on using the connect cache middleware. Furthermore you will also want to ensure that the cache module is after this module as the url, including the query string, is used as a key into the cache (thanks to jmarca for pointing this out). Current this middleware proxies the res.writeHead method. This is limiting and will will potentially raise exceptions for apps that simply call end.
