Here is a shot at what I am working on.
This is an "Email to a Friend" thing.
Thanks to anyone that can get me in the right direction.  And explain why I
shouldnt use HTTP_REFERER.


###  dtml-method>'Form to collect the email and comments'  *using Formulator
###  ***NOTE: line 2 captures the referring URL in 'emailthisURL' ****
###  POST to the method below.
###
<dtml-var "form.header()">
<input type=hidden name="emailthisURL" value="<dtml-var
"REQUEST['HTTP_REFERER']">">
<table border="0" cellpadding="0" cellspacing="0">
    <tr>
      <td>Friend's Email</td>
      <td> <dtml-var "form.email.render_from_request(REQUEST)"><dtml-var
requiredmark> </td>
    </tr>
    <tr>
      <td valign="top"> <br>Web Page URL that will be sent: </td>
      <td><dtml-var "REQUEST['HTTP_REFERER']"></td>
    </tr>
    <tr>
      <td valign="top"> <br>Comments: <dtml-var requiredmark> </td>
      <td><dtml-var "form.comments.render_from_request(REQUEST)"></td>
    </tr>
</table>
<input type="submit" value="Submit Question">
<dtml-var "form.footer()">

### dtml-method>>>'Process the form data'   --assume the client accepts HTML
email for now.
### sends an HTML email with the page in the email
###  ***NOTE:  emailthisURL only prints its address, not its contents.
###
<dtml-sendmail smtphost="localhost">
From: email@address.com(URGENT)
To: <dtmal-var email>
Subject: Here is a page to reference.
<dtml-mime type=text/html>

<dtml-var comments>
<dtml-var emailthisURL>
!--this includes the URL but doesn't display it in HTML,
my guess is that this is a string that needs to be
converted to some kind of referring object--!

</dtml-mime>
</dtml-sendmail>
