IEWatch

IEWatch is a plug-in for Microsoft Internet Explorer that allows capturing HTTP traffic and analyzing HTML code. Designed for web developers, site administrators and quality assurance engineers IEWatch is the most essential web development tool to get the job done fast and efficiently.
IEWatch unlocks the hidden HTTP data stream that is sent from the web browser to the server, revealing HTTP headers, Cookies, GET queries and POST data. Even data sent over secure HTTPS can be viewed in unencrypted form. IEWatch allows the most extensive filtering, including filters on HTTP headers and response content.
IEWatch can display HTTP duration information in a timeline chart. You can use the timeline chart to spot performance bottlenecks and to tune the performance of your web site.
The HTML code window features color syntax highlighting and a breakdown of the HTML elements such as images, links, forms, flash objects and scripts.
The innovative 'HTML Spotlight' feature allows quick pinpointing of the HTML code. No more searching through pages of HTML source, just click in the web page and IEWatch will highlight the section of HTML code you are looking for.
