Subject to errors and modifications:
The corresponding link would then have to be inserted in the
page as follows:
<a
href="http://wut.hs2/webioback.htm<w&t_tags=session>"
target="_top">Testlink
</a>
When the link is opened, the Web-IO replaces the session tag with
the session ID and passes it to the newly opened Web site.
To use the session ID for a back link, a small Javascript must be
inserted into the external page which accepts the session ID
when opening the page and inserts it in the back link.
<html><head>
<script language="JavaScript">
session=window.location.search
function setbacklink() {
var backlinkurl = "http://172.16.232.17/index.htm";
var backlink = backlinkurl.concat(session);
window.location.href = backlink;
}
</script>
In the body area of the page the function
setbacklink
can be used
as a hyperlink.
</head><body>
A test page is now opened with the passed session. <a href="javascript:setbacklink();"
>Open
test page</a>
</body></html>
This ensures that the access authorization remains intact after
jumping back to the Web-IO.
