This proxy captures the web application&#8217;s JavaScript code as it is being sent to a browser and rewrites the code to insert extra instrumentation code. The injected instrumentation code runs with the rest of the web application inside the end-user&#8217;s browser and can capture performance, call graph, application state and user interaction information, providing visibility directly into the last hop of the user&#8217;s experience.<\/p>\n<p>Because Ajax View is rewriting web application code dynamically each time a user visits the web site, it can:<\/p>\n<ul>\n<li>Serve different instrumentation code to different users. This allows us to distribute instrumentation code across many users, spreading the cost of gathering lots of information such that no single user pays a high performance penalty.<\/li>\n<li>Adapt an instrumentation policy and serve different instrumentation code over time.

Just browse to the site and then return to the Ajax View main page to see the statistics.<\/li>\n<\/ul>\n<h2>How It Works<\/h2>\n<p>Ajax View works by using a proxy to intercept and rewrite the JavaScript code of a web application and automatically inject instrumentation code.\u00a0 The rewriting is controlled by one or more instrumentation policies, embedded within the proxy.<\/p>\n<p>In this demo, you have seen a simple performance profiling policy that adds log statements to the beginning and end of every script block and function definition within the JavaScript code of a web application.\u00a0 This rewriting policy takes a script that looks like:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-276654\" src=\"https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2007\/04\/ajax_code1.png\" alt=\"ajax_code1\" width=\"317\" height=\"90\" srcset=\"https:\/\/www.microsoft.com\/en-us\/research\/wp-content\/uploads\/2007\/04\/ajax_code1.png 317w, https:\/\/www.microsoft.com\/en-us\/research\/wp-content\/uploads\/2007\/04\/ajax_code1-300x85.png 300w\" sizes=\"(max-width: 317px) 100vw, 317px\" \/><\/p>\n<p>And turns it into a script that looks like:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-276657\" src=\"https:\/\/www.microsoft.com\/en-us\/research\/uploads\/prod\/2007\/04\/ajax_code2.png\" alt=\"ajax_code2\" width=\"327\" height=\"170\" srcset=\"https:\/\/www.microsoft.com\/en-us\/research\/wp-content\/uploads\/2007\/04\/ajax_code2.png 327w, https:\/\/www.microsoft.com\/en-us\/research\/wp-content\/uploads\/2007\/04\/ajax_code2-300x156.png 300w\" sizes=\"(max-width: 327px) 100vw, 327px\" \/><\/p>\n<p>Our prototype actually does a little more rewriting than is shown here.\u00a0 For example, it inlines the logging functions to reduce performance overhead, rewrites return statements, and keeps track of the line number and character offset of the function to help identify anonymous functions and disambiguate functions with the same name.<\/p>\n<p>Whenever the injected instrumentation logs an event, such as a function enter or exit, the event is timestamped and added to a queue. A timer event handler periodically empties the queue of messages and reports them back to the proxy via an HTTP post request.\u00a0 The proxy is responsible for analyzing the results and generating the per-function performance statistics.<\/p>\n<h2>Conclusion<\/h2>\n<p>You have used the Ajax View proxy to gather performance profile information for a web application, without modifying the original web application, and without installing any extra plugins, ActiveX controls or extensions in the web browser.<\/p>\n<p>As Ajax View is currently an early research prototype, we are considering several future directions for the project, including further research into instrumentation policies to help developers debug their application, and the possibilities of integrating this technology into developer tools and\/or web server infrastructure.<\/p>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/li>\n\t\t\t\t\t\t<li class=\"m-0\">\n\t\t\t<h4 class=\"accordion-header\">\n\t\t\t\t<button\n\t\t\t\t\tclass=\"btn btn-collapse m-0\"\n\t\t\t\t\ttype=\"button\"\n\t\t\t\t\tdata-mount=\"collapse\"\n\t\t\t\t\tdata-target=\"#collapse-4\"\n\t\t\t\t\taria-expanded=\"false\"\n\t\t\t\t\taria-controls=\"collapse-4\">\n\t\tSend Us Feedback\t\t\t\t<\/button>\n\t\t\t<\/h4>\n\t\t\t<div class=\"collapse\" id=\"collapse-4\">\n\t\t\t\t<div class=\"accordion-body\">\n\t\t\t\t\t\t\t\t\t\t<ul>\n<li><a href=\"mailto:ajaxview@microsoft.com\">ajaxview@microsoft.com<\/a><\/li>\n<\/ul>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/li>\n\t\t\t\t\t\t<li class=\"m-0\">\n\t\t\t<h4 class=\"accordion-header\">\n\t\t\t\t<button\n\t\t\t\t\tclass=\"btn btn-collapse m-0\"\n\t\t\t\t\ttype=\"button\"\n\t\t\t\t\tdata-mount=\"collapse\"\n\t\t\t\t\tdata-target=\"#collapse-5\"\n\t\t\t\t\taria-expanded=\"false\"\n\t\t\t\t\taria-controls=\"collapse-5\">\n\t\tDownloads\t\t\t\t<\/button>\n\t\t\t<\/h4>\n\t\t\t<div class=\"collapse\" id=\"collapse-5\">\n\t\t\t\t<div class=\"accordion-body\">\n\t\t\t\t\t\t\t\t\t\t<ul>\n<li><a class=\"msr-external-link glyph-append glyph-append-open-in-new-tab glyph-append-xsmall\" href=\"http:\/\/code.msdn.microsoft.com\/\/ajaxview\" target=\"_self\" rel=\"noopener noreferrer\">Microsoft Visual Studio AJAX Profiling Extensions Power Tool<\/a><\/li>\n<li><a href=\"https:\/\/www.microsoft.com\/en-us\/research\/download\/ajax-view-javascript-instrumentation-proxy\/\">Ajax View JavaScript Instrumentation Proxy<\/a>\u00a0(first release of our client-side prototype)<\/li>\n<\/ul>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/li>\n\t\t\t\t\t\t\t\t\t<\/ul>\n\t\t<\/div>\n\t\t\n","protected":false},"excerpt":{"rendered":"<p>Ajax View enables developer to see and control the behaviors of their web applications on user&#8217;s desktops. &nbsp; &nbsp; News April 29, 2009: The technology in Ajax View is now available as a Power Tool: Microsoft Visual Studio AJAX Profiling Extensions.
