PipeBoost™ Header Retrieval Tool will let you analyze the HTTP response headers that are sent by any website. It will also help in determining what exactly gets compressed and what does not. We did not package this tool into the standard PipeBoost installation. This tool uses the winhttp5.dll from the Microsoft Windows HTTP Services 5.0 SDK. Microsoft has recently terminated the support of the WinHTTP 5.0 SDK, but you can download the required DLL below.

Download location:
http://www.pipeboost.com/downloads/HTTPGet.exe

Runtime Download: (Part of HTTP Services SDK)
http://www.pipeboost.com/downloads/winhttp5.dll
(Please place this file into System32 directory and
register it with regsvr32.exe)

This tool is now also distributed with PipeBoost. You can download and install a trial version of PipeBoost but keep this tool for as long as you like.

Note: The first HTTP request takes longer to execute, due to DNS name resolution.
