XMLHTTP Automation proxy

Troubles_In_Paradise

Hi guys, I've one question about proxy.
I use an Automation variable to make a connection to a web site to dowload an xmlfile (see code below... process runs via RTC).

Name	DataType	Subtype	Length
XmlHttp	Automation	'Microsoft XML, v6.0'.XMLHTTP60	

IF GUIALLOWED THEN
  Window.OPEN('do you want to start?');

IF ISCLEAR(XmlHttp) THEN
  CREATE(XmlHttp);

XmlHttp.open('GET',"www.mysite.com",FALSE); 

XmlHttp.send; 
IF XmlHttp.status = 200 THEN BEGIN
...

My question is, is there a way to force nav to use a specific proxy?
I've searched the forum and I found this post: viewtopic.php?f=32&t=46478&hilit=proxy+xmlhttp
Here they use .setProxy method that is not available for Xmlhttp variable but only for serverXMLHTTP.
Since I don't know the difference between XMLHTTP and serverXMLHTTP :oops: I simply tried to change the subtype of my automation variable from the first to the latter but with this modification RTC replies with "Application timed out".
has anyone an idea?

Thanks in advance.

I did another test:
Variables:

Name	DataType	Subtype	Length
XMLHTTP	Automation	'Microsoft XML, v6.0'.ServerXMLHTTP60	
XMLDOC	Automation	'Microsoft XML, v6.0'.DOMDocument

Code:

IF CONFIRM('Let''s go') THEN BEGIN

  IF ISCLEAR(XMLHTTP) THEN
    CREATE(XMLHTTP);

  IF ISCLEAR(XMLDOC) THEN
    CREATE(XMLDOC);
 
  XMLHTTP.setProxy(2,'proxy::8080');
  XMLHTTP.open('POST','http://www.google.com',FALSE);
  XMLHTTP.send;

  XMLDOC.load(XMLHTTP.responseXML);
  XMLDOC.save('C:\Temp\test.xml');

  MESSAGE('done');
END;

but I receive the following error:

---------------------------

This message is for C/AL programmers:

The call to member open failed. msxml6.dll returned the following message:
The parameter is incorrect.

Changing Approach I found a solution.
This is the post that helped me: viewtopic.php?f=23&t=37522&hilit=winhttp
Variables used:

Name	DataType	Subtype	Length
WINHTTP	Automation	'Microsoft WinHTTP Services, version 5.1'.WinHttpRequest	
_InStream	InStream		
URL	        Text		1024
Received	Text		128

Code:

IF CONFIRM('Let''s go!') THEN BEGIN

  URL := 'http://www.google.com';
  
  IF ISCLEAR(WINHTTP) THEN
    CREATE(WINHTTP);

  WINHTTP.SetProxy(2,'myproxy:8080');
  WINHTTP.Open('GET',URL,FALSE);
  WINHTTP.Send;

  CLEAR(_InStream);
  IF WINHTTP.Status = 200 THEN BEGIN
    _InStream := WINHTTP.ResponseStream;

    //do what you want
    _InStream.READTEXT(Received,128);
    MESSAGE(Received);
  END;
END;

Hi,

I am aware of this thread is old, but I had an issue in this direction.

The solution with XMLHTTP should also work, if you use only one colon ':', maybe that was only a typo.

So instead of

XMLHTTP.setProxy(2,'proxy::8080');

you have to set

XMLHTTP.setProxy(2,'proxy:8080');

and it should work.

It seems also to me that the current user credentials are used, because I do not need to setup these information.

Kind regards,
