[webkit-dev] Regarding WebKit Support Libraries

Hi Alp and Brent,

My vote is to use Wininet.

This is because my objective is to eventually support a WinCE version.
Wininet is used in both Win32 and WinCE, so it is a convenient choice from
this point of view.

CURL would be OK if it could be easily ported to WinCE.  I haven't looked
into that, so I don't know the difficulty.  But, I suspect it is
non-trivial.  Also, it would have the downside of requiring extra code which
increases the static application size.  (Static application size is an
important consideration for mobile use cases).

So, I vote for using Wininet.  There was Wininet support in the codebase
earlier.  I believe this could be resurrected without too much trouble.
