I wanted a general way to do this, that did not rely on the page being
hosted by On-Rev, so I worked out how to do this using PHP as well as
On-Rev.

You can check out the On-Rev version at
<http://www.troz.net/rev/revweb.irev?revlet=System>.

I edited the html produced by the standalone builder and added this line:
	pageLocation="<?rev put $_SERVER["SERVER_NAME"] & $_SERVER["REQUEST_URI"]; ?>"
This was inserted into the <embed> tag, on the line just after the instanceID.

In the revlet, I used this script to read the parameter:
      put the revletParams of this stack into tParams
      put tParams["pageLocation"] into tPageLocation

Then I was able to format the string the way I wanted. It includes the
page name at this stage e.g. "www.troz.net/rev/revweb.irev"
so I set the itemDelimiter to slash, removed the last item, added the
"http://" and then I was left with the containing folder.

For the PHP equivalent, you will need to change the file extension of
the html file to ".php" and instead of the irev line above, use this:
	pageLocation="<?php echo $_SERVER["SERVER_NAME"].$_SERVER["REQUEST_URI"]; ?>"

This gives exactly the same data in exactly the same format, so the
processing can be the same.

So now I have a way to include media in a revlet, using relative addressing :-)

Cheers,
Sarah
