Memory Leak in Winhttp 6.1 routine WinHttpSendRequest() on Windows 7

Question

I posted the following issue in microsoft.public.winhttp of https://groups.google.com/forum/#!forum/microsoft.public.winhttp with topic "Memory Leak in WinHttpSendRequest()".

I believe this WinHttpSendRequest() function is still producing memory leak in Windows 7 (WinHttp 6.1), here what I have: 

Platform: Windows 7 Enterprise (version 6.1 SP1) 64 bit platform. 

WinHttp: version 6.1.7601.17514. 

Visual Studio version: Microsoft Visual Studio Ultimate 2013, Version 12.0.31101.00 Update 4. 

Memory leak detect tool: perfmon, using "private bytes". 

Symptom: With calling WinHttpSendRequest() memory keep increasing even though it looks like a square, but the trend is going upward. Without calling WinHttpSendRequest, the trend is pretty much flat line even though it looks like a square. 

The following is the code,
