As described in Detail in this MSDN article the JScript garbage collector in previous versions of Internet Explorer manages the lifetime of JScript objects but not of DOM objects. As a result, the JScript garbage collector can not break Circular references between DOM objects and JScript objects, and memory leaks may occur.
Programmers who need to support older versions of the Internet Explorer browser should still try to pay attention to programming patterns such as JScript closures, as they could cause memory leaks.
IEJSLeaksDetector is a plain, native, Windows application and does not require any particular setup (the executable can be just unzipped and run).
It only runs in 32 bit versions of Windows. 64 bits editions are not supported yet.
There are only two installation steps required to make sure that the tool works correctly:
1. The tool requires that the pdm.dll script installer is installed in the machine. This DLL is normally installed with any version of Microsoft Visual Studio.In case you are unable to install Visual Studio in the target machine, a simpler way to install Pdm.dll is by installing the Microsoft Script Debugger, freely Downloadable here .
2. The tool also requires Internet Explorer script debugging to be enabled to work correctly. Verify that the check box "Disable script debugging (Other)" is unchecked, in IE ('Tools' menu -> Internet Options -> 'Advanced' tab -> 'Browsing' section) as shown in figure.
How to use the toolThe user can start the memory profiling of a web application navigating to the desired URL. A new tab is opened with a WebBrowser control and a tree view shows all the documents and scripts that compose the current page.
When the user has finished to interact with the page he can click the "Stop" button, which causes the tool to close the control and track possible leaks.
More information can be found in the Docs ENCLOSED with the Binaries .
