In real bits, URL get returned to We script like this:
Res://shdocvw.dll/http_404.htm#http://www.docurl.com/bar.htm

For testing Use Docurl = "res://shdocvw.dll/http_404.htm#https://www.microsoft.com/bar.htm"
Docurl=document. URL;

This is where the HTTP or https'll is, as found by searching for://But skipping the res://
Protocolindex=docurl.indexof ("://", 4);

This finds the ending slash for the domain server
Serverindex=docurl.indexof ("/", Protocolindex + 3);

For the HREF, we are need a valid URL to the domain. We Search for the ' # symbol to find the begining
The true URL, and add 1 to skip It-this is the Beginurl value. We use Serverindex as the end marker.
Urlresult=docurl.substring (Protocolindex-4,serverindex);
Beginurl=docurl.indexof ("#", 1) + 1;
Urlresult=docurl.substring (Beginurl,serverindex);

For display, we need to skip http://, and go to the next slash
Displayresult=docurl.substring (Protocolindex + 3, serverindex);
document.write (' <a href= ' + Escape (urlresult) + ' > ' + displayresult + "</a>");
