Assume that you develop an application that makes use of the WinHTTP Web Proxy Auto-Discovery Service (WinHttpAutoProxySvc) or calls the WinHttpGetProxyForUrl function. When you run this application on a computer that is running Windows 7 or Windows Server 2008 R2, you encounter a memory leak issue.
Note The memory leak issue is in the WinHTTP Web Proxy Auto-Discovery Service (WinHttpAutoProxySvc) host process. The issue occurs when the WinHttpGetProxyForUrl function is called. Therefore, the memory usage of the process increases every time that the WinHttpGetProxyForUrl function is called.
This issue occurs because the cleanup code is not executed in DLL_PROCESS_DETACH when the Jscript.dll file is dynamically unloaded.
