However i am not at all friendly with the certs.I need some help regarding certs.I need to make a request to https management port .After adding tthe default cert to the browser i can access it. But through application i cannot . So to add those certs in the application, which file i need to add in my application . And how to create those file with the default cert which i am getting from the browser? How can i import those certs in my application? Thanks in advance Regards
