I'm developing a single page application with a PHP backend using Slim Framework and a JavaScript frontend client using Backbone.js and came across a situation where I want to log requests that result in a 404 error but knowing that hash fragments are not recorded in the request on the backend. I'm wondering if there is a work-around.
My first thoughts was to have JavaScript write a cookie with the hash fragment and have PHP read that for logging.
For logging I'm using a custom Monolog handler for Doctrine 2.
This is what I use for sending those fragments off to Google Analytics or off to my error reporting system:
var url = Backbone.history.getFragment();
if (!/^\//.test(url)) {
url = "/" + url;
}
