• Apache proxy: (502)Unknown error 502: proxy: pass request body failed

We need to make requests to a server and these requests have to come from a fixed IP address and be authenticated via SSL. For this purpose we set up a EC2 instance to function as a proxy. We can make cURL requests using our key and certificate from the proxy machine successfully. But when we go through Apache we get:
“(502)Unknown error 502: proxy: pass request body failed”

• Backbone’s views’ $el contains all matched elements

If you initialize a Backbone view with an el selector that matches more than one element: within the view $el will refer to a jQuery collection that contains all the matched elements, while el will contain the DOM object for only the first element matched. To achieve consistency, you might want to instantiate your view like so:

new view({el: '.selector_that_matches_many:eq(0)'});
