IE 11 deprecated features and alternatives 

 As Microsoft ends support for older browsers like IE 8,9,10 and only the most current version of Internet Explorer available for a supported operating system will receive technical support and security updates. Internet Explorer 11 is the last version of Internet Explorer, and will continue to receive security updates, compatibility fixes, and technical support

  •      navigator.userAgent, navigator.appName :  These method values are changed in IE11. so, we should modify the code accordingly.
  •    Request.Browser will not work
  •    ActivexObject will not work
  •   MSIE identifier removed from the user Agent
  •   document.all is no more exist
  •    attachEvent will not work  - we must use addEventListener alternatively
  •     window.execScript  will not work – alternatively we must use eval()
  •     window.doScroll  will not work- alternatively we must use window.scrollLeft, window.scrollTop
  •   document.fileSize, img.fileSize no more exist - use XMLHttpRequest
  •   script.onreadystatechange and script.readyState - script.onload
  •   document.selection - window.getselection
  •   document.createStyleSheet no more exist – alternatively we use document.createElement
  • window.createPopup  no more exist - alternative use div or iframe with a high z-Index value


Starting with IE11, the navigator object supports plugins and mimeTypes properties. In addition, the window.ActiveXObject property is hidden from the DOM. (This means you can no longer use the property to detect IE11.)

IoT technology The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines.  IoT is a network of sensors where data is exchanged, using different connectivity protocols, with systems. This set up can be leveraged to create a new business application or to enhance an existing process. The exchange of the data can be bi-directional between sensors and systems Examples of sensors can be temperature sensors, motion sensors, flow meters, heart meter monitors, biometric devices, smoke detectors, & etc Examples of connectivity can be wifi, radio, GPRS, GSM, LAN, WAN, & etc. Examples of systems can be a remote health monitoring applications, SCADA applications, etc Look at next slide about the complete flow of IoT process Examples A doctor in US would like to monitor the heart rate and ECG of a patient in Hyderabad. This is done with the patient having sensors attached to him that collect the ECG data and the hea...

  What is a reverse proxy? A reverse proxy is a server that sits in front of web servers and forwards client (e.g. web browser) requests to those web servers. Reverse proxies are typically implemented to help increase  security ,  performance , and reliability . In order to better understand how a reverse proxy works and the benefits it can provide, let’s first define what a proxy server is. What’s a proxy server? A forward proxy, often called a proxy, proxy server, or web proxy, is a server that sits in front of a group of client machines. When those computers make requests to sites and services on the Internet, the proxy server intercepts those requests and then communicates with web servers on behalf of those clients, like a middleman. For example, let’s name 3 computers involved in a typical forward proxy communication: A: This is a user’s home computer B: This is a forward proxy server C: This is a website’s origin server (where the website data is stored) In a stand...
