Custom HTTP header
[1/5] from: francis:franfran at: 24-Oct-2010 20:55
Hi,
I am a new comer in Rebol world, and would like to ask a question about
block.
If I want to download a page with a custom HTTP header, I could do:
>>
read/custom http://192.168.1.100:8080 [
header [
Cookie: "a=1234"
Referer: "http://www.xyz.com"
]
]
However, if I want to assign the header as a word first, the following won't
work.
>>
custom-header: [
Cookie: "a=1234"
Referer: "http://www.xyz.com"
]
read/custom http://192.168.1.100:8080 [ header custom-header ]
It is because the custom-header got evaluated rather than passing as data,
and I could confirm this by:
>>
print cookie
a=1234
May I know how can I solve this problem by using the correct syntax?
Thank you very much!

Try something like this:
custom-header: [
Cookie: "a=1234"
Referer: "http://www.xyz.com"
]
read/custom http://192.168.1.100:8080 append/only [header]
custom-header

Hi Sunanda,
Thx for the direction of append command, it works.

If you're code is in a function, you'll want to include a COPY in
there, use JOIN, or something else.
read/custom http://192.168.1.100:8080 append/only copy [header] custom-header
read/custom http://192.168.1.100:8080 join [header] [custom-header]
read/custom http://192.168.1.100:8080 rejoin [[header] custom-header]
; Thanks to Ladislav for reminding me about REJOIN with an initial
block arg.
hdr: [header []]
hdr/header: custom-header
read/custom http://192.168.1.100:8080 hdr

Well, while we're at it...
reduce ['header custom-header]
compose/deep [header [(custom-header)]] ; copies custom-header
compose/only [header (custom-header)]
