Also, if there is no content, then the content-length header is not 
set ... 

Here's my suggested changes at the bottom 


http://rebol.wik.is/Rebol3/Schemes/Http/Prot-http.r/Make-http-request

1.1 didn't work since chunked encoding was broken, so they reverted 
to 1.0. Proper 1.1 support is on the list to fix.

However, chunked encoding needs to be fixed first, before 1.1 support 
can be reenabled.

The .rlp http client was also written before the Unicode changes 
were finished, so we need to review for those fixes too.

That would affect the string-vs-binary situation.

I'm looking at the .r source ...

Which has only been patched a few times, not yet properly reworked.

well, I think not setting the content-length header might be bug 
..

eg .. with the HEAD verb

Only if you aren't using chunked encoding. If you are, then setting 
Content-Length would be a bug.

Is this going to be rewritten so that we can stream files using PUT?

Sure. And it's going to be rewritten so that http server mode is 
supported too.

In an event handler sort of way though - no assumptions that there 
are going to be files that are being served. You could build a new 
Cheyenne on it, but it won't compete with Cheyenne itself.

It's more for web service application control interfaces than it 
is for generic web serving.

actually where is stuff defined anyway?  It appears in prot-http.r 
but it's not there when your probe the scheme...

Just thinking that if you need to create signed headers eg. for Amazon 
requests, then these functions should be readily accessible rather 
than tucked inside a scheme somewhere

Just had another thought, if the headers already contain a content-length, 
then make-http-request should not set it again ...

This would be where you are PUT ing a binary file and you already 
know the length, so you set it in the spec ...

All the stuff is defined in the http module - it's the only part 
if the internals that has been put in a module, so far.

Clarification: The http server mode is meant to be good enough for 
Doc to build an R3 Cheyenne on. If he feels the need to bypass it 
and go down to the tcp level, that would be a failure.

so would I access make-http-request ?

I can't say right now - ask me again tomorrow.

what I need is a function that traverses all the objects to find 
a function ....

Going out :)

running away from me??  Happens a lot :(

It's just a fling - I'll be back :)

my candle will still be burning ...

For instance, in writing the AWS stuff, Maarten basically had to 
write his own http scheme ... because it wasn't easy to reuse the 
existing stuff.

I hope we can avoid that need for r3

if you look at the port object! after eg. opening rebol.com, there 
is a port/scheme/actor object, and then the actor object seems to 
be duplicated in port/actor ...

Is there actually any documentation on using the http apart from 
read ?

http://www.rebol.net/docs/HTTPScheme state diagram.png

Just a question about eg.

open http://www.rebol.com


Does 'open take the url, turn it into a port object, and then invokes 
the http scheme'' open on the port object?

scheme's 'open on the port object?

actually what is the question ? :-)

it's doing what you noted, so what ?

just a stream of consciousness like Marcel Proust

:-)

So, if you write your own schemes ... open must invoke the correct 
'open some how

looks like 'open is a native ... no source given

you're seeking the proto-open ?

still streaming ..

AFAIK there's virtually no R3 documentation

i think you know this source system/intrinsic/make-port

ahh.. that helps

there's no trace/net ?

I guess it's download wireshark time :(

this was from ...

but probe r

well I guess it tells me something is there .. as I don't get an 
error.  But 9831 is not very useful content.
