Answer : You should use: headers('X-TotalPages') (Posting Wawy's answer so the question can be resolved.) For $http(url).then() syntax which replaced $http(url).success().error() in newer versions of AngularJS, I used this: $http(url).then(function(response){ response.headers("X-TotalPages"); }); Just using response.headers() will give all headers attached in response.

Answer : I had this issue - I found that setting the loop option to false resolved it for me. So, I've been banging my head over this cloning issue with passing click events to the cloned slide.... what finally solved it for me is to set these two config values: loop: false, rewind: true This will allow the carousel to still loop around but not duplicate slides. Get ready for Awesome solution of this problem: If you want to set loop:true in case of having more than particular number of items (in my case i am using 5 items on a screen, total scrollable items are 15) loop: ( $('.owl-carousel .items').length > 5 ) Above solution will not run loop in case of having less than 6 items while loop will be enabled automatically in case of having more than 5 items. This solved my problem, i hope, this will also help you. Thanks for asking this question and enjoy this code :)

Answer : I think the problem is about security groups of your instance. To the best of my knowledge you need to allow the traffic on the security group associated to your EC2 instance. If you are using memcached the port is 11211 if redis the port is 6379 Try to have a look to the AWS official documentation. http://docs.aws.amazon.com/AmazonElastiCache/latest/UserGuide/GettingStarted.AuthorizeAccess.html I hope this helps somehow. First, check the instance security group and check port 6379 is allowed in Inbound. After that, check your default VPC security group and add inbound rule Custom TCP Rule-6379-Anywhere and save. I hope this will fix the issue. Actually solution is to add security group to elasticache cluster, and this security group should allow 6379 port.
