Something I'd forgotten ... but you can set custom headers using 
the header keyword.  Not documented though.

read/custom url [ header [ cookie: "blah blah" ]]

The header keyword is not needed if you do a post though.

Anyway, my async-fetch-s3object is now working :)

Oldes - "only if the string contains new line or " char" - that's 
wrong. It depends on the string length. also, mold escapes characters 
the REBOL way which you DON'T want.

>> "a long string"
== "a long string"

>> "a very long string with no newlines or quote characters, that 
still uses braces instead of quotes because it's long"

== {a very long string with no newlines or quote characters, that 
still uses braces instead of quotes because it's long}

the init function is called when the port is created from a url! 
or block! spec. eg. p: make port! ahttp://...

calling OPEN on a url! or block! spec also creates the port! first, 
so init is called.

So, after the port is created ..

i think the native code does some very basic initialization of the 
port! then it calls init

ok.  thanks.

Is there a good method to conditionally remove a char in a string 
without having to manage the string? That is: Find char X at location 
Y and remove it if it's there, otherwise just return the string as 
is.

good method = fast method

the first occurence only ?

yes, I was thinking of the case of removing a conditional comma at 
the tail of an assembled string as quickly as possible.

first occurrence = just one occurrence

something like...
head any [remove find string char string]

hmm.. yes, that might work, thanks

Parse  may be faster, though

especially within R3

hmm, the string is required to be present twice, but I guess that's 
ok.

Probably a little faster with R3...
also string remove find string char

Regarding Romano's atcp protocol, http://www.rebol.it/romano/atcp-protocol.r
 there is a little bug at the bottom of the page I think

He has 
		if find system/components 'ssl [
			net-utils/net-install 'assl self 0
			net-utils/net-install 'atsl self 0
		]

but I think he meant

		if find system/components 'ssl [
			net-utils/net-install 'assl self 0
			net-utils/net-install 'atls self 0
		]

Good catch, Graham

I emailed him.... hope he has time to spare from his Java development 
to fix it :)

Gab's async protocol, the awake event takes two parameters
Romano's atcp protocol, the awake event takes one parameter ....

Oldes, I get braces when string length > 50
>> mold loop 51 [append "" "."]
== {{...................................................}}

Graham, though, tls:// never worked in REBOL so... :)

Carl keeps saying otherwise :)

does anyone use str-enc-utils.r? I'm not sure if I have found a bug.

actually there is not just a bug, but also a hang.

>> str-enc-utils/iso-8859-15-to-utf-8 "aø"
== "" ; bad
>> str-enc-utils/iso-8859-15-to-utf-8 "ø"
== "ø" ; good
>> str-enc-utils/iso-8859-1-to-utf-8 "aø" ; hangs

Link plz...

http://www.rebol.org/view-script.r?script=str-enc-utils.r

hmm.. that one is newer. I have to test that one. one sec.

the hang is gone, but the other bug is still present.

nope, hang is not gone, just required some different letters to trigger 
it.

ascii: charset [#"^(00)" - #"^(7F)"]

ascii-rule: [
      copy transfer [ascii some ascii] ( ; <- problem
        head insert tail output-string transfer
      )
    ]


This rule does not look correct. I replaced [ascii some ascii] with 
[some ascii] and now it works.

This is present in two locations in the script, but I can't be entirely 
sure if my fix is correct.

Thanks, Henrik. Could you possibly let me know the binary of the 
strings that you saw the bug with. I suspect I am seeing something 
different in AltME.

I was having problems with beer being disconnected while doing any 
significant http work, and using Gab's async http seems to have solved 
it for me.

Graham, I may have a little more time to work with it soon (not sure 
yet). Can you make it working without docs?

Sure ... I wrote up an example

cool

http://rebol.wik.is/Protocols/Test-async-http.r

uses the same ahttp with a small change ... see http://github.com/gchiu/Rebol2/blob/master/Protocols/prot-ahttp.r

thanks

In the handler, there should be a check to see if the event is an 
error ...and then close the port

seems redirects are not supported

Yes, that's correct

I don't need redirects since I'm downloading from Amazon S3 ...
