RE: HTTP Get when a domain name returns multiple IP addresses

Hi Bruno,

Regarding your HTTP GET examples returning error 2;

The problem occurs when there is no other certificates (a kind of fallback

Code 4D :   View in english :   Voir en texte pour copie :
1 C_TEXT($vt_url;$vt_httpResponse)
2 $vt_url:="https://chrismeller.com;

4 C_LONGINT($vl_httpStatus)
5 $vl_httpStatus:=HTTP Get($vt_url;$vt_httpResponse)
6 ASSERT($vl_httpStatus=200;"http status : "+String($vl_httpStatus))
7
}

I think this issue is related to this bug:
ACI0096586"HTTP Get" request fails with certain https web sites

Which is fixed in Nightly Build 212638 of v15

I get the error you described with v15.4Hf1 and earlier
but no error when using v15.x 212638:

Can you try the latest nightly builds?

Yes, TLS sin is not supported.
The worrying part is that I expect TLS SNI to become more and more 
standard/common.

I reported this problem on taow in july 2016.

It has been discussed on the forum here :

Please vote.

That didn’t work, but we found (we think) it is that 4D doesn’t support Server 
Name Identification (SNI) which Amazon requires
Using your CURL plugin got us around the problem though- thanks!

HTTP Get when a domain name returns multiple IP addresses

[lists--- via 4D_Tech]

Hi,
we’re running a serverless API using Amazon Lambda, and 4D seems to fail on the 
DNS lookup as it returns multiple IP addesses
A dig gives you
api.universalcodes.msupply.org.nz. 25 IN A  52.84.207.226
api.universalcodes.msupply.org.nz. 25 IN A  52.84.207.186
api.universalcodes.msupply.org.nz. 25 IN A  52.84.207.19
api.universalcodes.msupply.org.nz. 25 IN A  52.84.207.198

api.universalcodes.msupply.org.nz. 25 IN A  52.84.207.209

A simple browser query works fine

but not from 4D
Any ideas appreciated.

Cheers,
