Is HAWHAW.NET a re-implementation of the PHP code?
No, the hawhaw.inc PHP library has been compiled as-is to a .NET assembly and on top of that just a set of custom webserver controls have been defined in order to perform a mapping from given ASP.NET tags to the according HAWHAW classes. This solution finally has been made possible by the extraordinary Phalanger project, that brings together both the PHP and the .NET worlds and allows the usage of HAWHAW in a native ASP.NET environment. There has been written no mobile-specific code at all for HAWHAW.NET, as all this functionality has been derived from the underlying hawhaw.inc library. This makes this approach very robust and future-proof, as .NET developers automatically will benefit from ongoing improvements done by the PHP community.
