Clone of improved wxCurl from OpenCPN. wxCURL is a simplified and integrated interface between LibCURL and wxWidgets.
As libCURL authors state, libcurl is free, thread-safe, IPv6 compatible, feature rich, well supported, fast, thoroughly documented and is already used by many known, big and successful companies and numerous applications.
wxCURL provides several sub-classes for simplified interfaces to HTTP, WebDAV, FTP and Telnet based resources, threads specialized for non-blocking downloads/uploads, stock download and upload dialogs.
