SYMPTOMS

You use the Windows Internet (WinINet) API in an application to send Hypertext Transfer Protocol over Secure Sockets Layer (HTTPS) requests to a server. In this situation, the memory usage of the application continually increases. This behavior indicates that there is a memory leak.

Note This issue only affects HTTPS requests.

CAUSE

This issue occurs because of an error in the WinINet API. When the application establishes a connection by sending HTTPS requests to the server, WinINet allocates 85 bytes to each request. However, 85 bytes for each request are not freed after the connection is established. Therefore, a memory leak of 85 bytes per request occurs.

RESOLUTION
