The Problem with CORS

Posted by & filed under Development, Javascript, Rant.

Cross Origin Resource Sharing (CORS) is intended to be revolutionary, empowering the web to push and pull data from everywhere.  In reality I see this causing more problems than helping anyone.  Note: I’ll use XMLHTTP instead of AJAX since the latter is so overloaded… 1. It breaks the cross-domain paradigm This is really all I […]

Parsing Querystring Values in Fiddler Custom Rules

Posted by & filed under Code, Development, Work.

  I’ve been hot-rodding Fiddler for some time now to make my life a lot easier when debugging my site tagging and analytics tracking requests.  You can customize just about anything within the sessions window from the color, background, custom columns to the request it actually makes.  I’d previously created a custom column called “EventType”, which […]

PhantomJS and asynchronous resources after load

Posted by & filed under Development, Javascript, Work.

I’ve been dabbling with PhantomJS for about the past 3 months and just “picked up my pen” again this week. I’m trying to write some automated testing around tag resources loading onto the page. page.open(url,function(status){ if(status==’success’){ var check = page.evaluate(function(){ return window._blah?true:false; }); } }); What I noticed was varying results as to certain tags being […]
