Source for SessionHandler is not available in github

[cado2010]

The nuget for uhttpsharp 0.1.6.22 includes a class SessionHandler that is not available in github.
I want the latest version of uhttpsharp source code to debug an issue I'm facing where the CookieStorage ctor fails with an Index out of range error due to incorrect assumption of number of entries in the parsed cookie header:

2017-05-20 11:48:20,298 WARN (HttpClientHandler-22)((null)) Error while serving : 127.0.0.1:53639
System.IndexOutOfRangeException: Index was outside the bounds of the array.
at uhttpsharp.CookiesStorage..ctor(String cookie) in c:\Users\shani\Documents\GitHub\uHttpSharp\uhttpsharp\IHttpContext.cs:line 66

Thanks!
