Advanced Http 1.1 Client using [coroutine]s

[CMcC] 28Feb09

The package is part of [Wub] and is named HTTP (to distinguish itself from the tcl library [http]).

The latest source can always be found here: [http://code.google.com/p/wub/source/browse/trunk/Client/HTTP.tcl]

The intent of this package is that it be more-or-less stand-alone, and that it be able to integrate into the [Wub] server so that domain code and utilities can easily make HTTP1.1 outbound connections to other servers (for use in, e.g. OpenId.)

The latest version is somewhat dependent upon [Wub] utilities for parsing Urls and creating HTTP-compatible dates.  These facilities should, arguably, be in [tcllib].  The package contains a small compatibility library to permit it to stand alone, but there's nothing better than having the originals.

One nice feature is that it uses RS's [know] facility to allow [[http://whatever]] to be recognised as a command to fetch the url.

Old version is in the [Half Bakery] here: [http://wiki.tcl.tk/_repo/HttpClient/]
