IE Memory Leaks

OutOfHanwell.com took the initiative to host Drip (a memory leak detector for Internet Explorer) after it was no longer available through Joel Webber's blog and has made some revisions to the tool under its BSD license.

If you wish to contribute or if you have specific thoughts or suggestions regarding the Drip tool, please visit the SourceForge project page.

Download

The latest version (see release notes for version 0.3 and version 0.4) can be downloaded from:

• Drip-0.4.exe: binary executable
• Drip-0.4-src.zip: source code

Drip's Limitations

Although Drip can catch the most common causes of memory leaks in Internet Explorer, there are certain memory leaks that occur outside the realm of the web page.

Specifically, pages with hidden table cells will leak memory when they are unloaded. This leak is not caused by JavaScript code, and it can only be avoided by capturing the "onbeforeunload" event and displaying all hidden table cells. Because only a small amount of memory is leaked, it is possible that certain pages can ignore this leak with no severe consequences.
