Resolution
In order to download a PDF file from a URL, the following sample code may be used:

USING OpenEdge.Core.*. 
USING OpenEdge.Net.HTTP.*. 
USING OpenEdge.Net.HTTP.Lib.ClientLibraryBuilder. 

DEFINE VARIABLE oRequest AS IHttpRequest NO-UNDO. 
DEFINE VARIABLE oResponse AS IHttpResponse NO-UNDO. 
DEFINE VARIABLE oRequestBody AS WidgetHandle NO-UNDO. 
DEFINE VARIABLE oResponseMemptrEntity AS OpenEdge.Core.Memptr NO-UNDO. 
DEFINE VARIABLE oByteBucket AS OpenEdge.Core.ByteBucket NO-UNDO. 

oRequest = RequestBuilder:GET ("http://server:port/afile.pdf") 
:AddHeader("Authorization","Basic YT...YXI=") 
:Request. 

oResponse = ClientBuilder:Build():Client:Execute(oRequest). 

oByteBucket = CAST(oResponse:Entity,OpenEdge.Core.ByteBucket). 
oResponseMemptrEntity = oByteBucket:GetBytes(). 

COPY-LOB FROM oResponseMemptrEntity:Value TO FILE "c:\temp\afile.pdf".


Although the aim of this code is to show a way of downloading a PDF file from an ABL code, this code can be actually used to download other types of files as well. Use this code just as a sample and starting point.​
