Four Web Applications That Need Real Browser Monitoring Part – 1

A few look into four Web applications on sites where real browsers matter. These good examples highlight how the end-user experience can be captured only with Web performance-monitoring technologies involving a (real) browser: my browser’s page

Presently there are many reasons to do ongoing testing and monitoring with a solution that uses a real-browser rather than an fake browser. An important reason is the ability to accurately capture a real high-fidelity bitmap of the web page when an error occurs rather than a reconstructed web page. A bitmap of a page is made when you take a screenshot of the actual site exactly as it is drawn by the internet browser. A reconstructed page endeavors to recreate design of the page by translation the captured HTML.

Alternatives that use imitation-browser screening are forced to catch the HTML of a page when an mistake occurs, since they do not actually draw or construct the page during the test. If you use an imitation internet browser to try to view the page that made the error, you will definitely get a reconstructed page. While this works for simple programs, sites that use RIA technologies such as DHTML will not work with imitation-browsers. A real-browser-testing product captures the actual page that the user sees in a bitmap

For taking the Web page exactly as the consumer would experience it, you may need (realbrowser) technology that captures the real dynamic behavior of the Web site.

When procedure managers see a performance issue they want to quickly resolve the challenge to reduce the number of users who could be impacted.

An imitation web browser that captures individual things would make an hard work to reconstruct this image by assembling objects via HTML, a process that can be error vulnerable and can bring about a misleading analysis. Screen renovation would have extreme difficulty displaying the DHTML tendencies employed by a site like Pottery Barn.

Using an imitation browser is like reconstructing a crime field from someone’s memory from it. Using (real)browser technology is much like by using a surveillance camera for taking a snapshot of the actual crime scene.
