R3 HTTP implementation docs posted
When Gabriele implemented the R3 alpha HTTP protocol, he wrote it using his embedded document/code process. Although the R3 HTTP scheme source code has been published for a long time, the embedded comments were filtered out in the construction process, and as far as I know, never got published anywhere.
For those of you who want an inside peek at how this source code works, here's the actual REBOL 3 HTTP protocol scheme documentation (including inlined source code.)
Note that this is older code/comments, but I think it's still 99.9% accurate.
