Thank you - I guess, then(?), it would not be a "bad" practice to substitute the AcitveX HTTP for the HTML HTTP!

I don't even know if there is a difference between the two! But with the activeX service the URL does not seem to show in the status bar.

Does JavaScript have (try/catch)? Something new every day.

>>My project includes a browser. The project script usually makes HTML HTTP requests. The browser creates a reference to MSDOM using javascript (ex):
var oXML=new ActiveXObject("MSXML2.DOMDocument.4.0")

var oHTTP=new ActiveXObject("MSXML2.XMLHTTP")
