It makes some assumptions about the application and stack implementations. Therefore, it will not work with every application or with every stack. NEC USA has only tested SocksCap32 with Microsoft's 32-bit stack. The best way to find out is to try it. Refer to the scorecard of applications and stacks with which SocksCap users have reported success or failure.
Volunteers provide the information in the scorecard.
The list is not complete and quickly becomes outdated. We greatly appreciate your additions and updates to the scorecard. If SocksCap16 sees a request come from an application run prior to starting SocksCap16, it attempts to make all connections directly for that application. Beware that the application may become unstable. Start SocksCap16 before other WinSock applications.
