This SDK makes the Internet software you write working from behind a proxy. This is essentially a developer's version of the HTTPort application. The package includes client DLLs, server binaries, samples in C and VB with source, header files and COM wrapper for C++ and VB with source.

In Version 1.3.18, the HTTPort DLL has the 'lost last send' bug fixed. The HTTHost server is updated so as to prevent situations when the rapidly sending client hits the local buffering limit and gets disconnected.
