Request.ServerVariables("SCRIPT_NAME") with a parameter?

[snix1]

I have the following form. It is a "passive" login. This form is in a sidebar of my site. The user logs in and all the action does is store a cookie, then return to the page you're on. It works fine except when the page the user is currently viewing when they decide to log on has a parameter attached to it:

http://www.mysite.com?id=2.

The "ref" input value in the form tells the action where to redirect to, but how do I append the parameter to the value? I'm relatively new at ASP and was wondering if anyone could help. I get errors if the parameter is not present, of course. I hope this makes sense. Thanks!

<form method=&quot;post&quot; name=&quot;loginform&quot; action=&quot;/login/login_action.asp&quot;>
<table>
<tr>
<td class=&quot;whiteletter&quot;>Username:
</td>
<td><input name=&quot;username&quot; type=&quot;text&quot; size=&quot;5&quot; maxlength=&quot;50&quot;>
</td>
</tr>
<tr>
<td class=&quot;whiteletter&quot;>Password:
</td>
<td><input name=&quot;password&quot; type=&quot;password&quot; size=&quot;5&quot; maxlength=&quot;50&quot;>
</td>
</tr>
<tr>
<td class=&quot;whiteletter&quot;>
<input style=&quot;background-color : white; font-size : 8pt&quot; type=&quot;submit&quot; value=&quot;GO&quot;>
</td>
</tr>
<input type=&quot;hidden&quot; name=&quot;ref&quot; value=&quot;<%=Request.ServerVariables(&quot;SCRIPT_NAME&quot%>&quot;>
</form>

Thanks so much for your response. But don't I have to have the &quot;?&quot; in there somewhere. Maybe this would work:

<%=Request.ServerVariables(&quot;SCRIPT_NAME&quot%><% if not isnull(Request.QueryString) then Response.write(&quot;?&quot & Request.QueryString end if%>

Maybe my ASP isn't so clean, though. Does this make sense?

Yeah sorry wasn't (and still aren't) thinking straight - I should have tested what I wrote.

You are correct.

Great! Here's what I have now in my &quot;passive&quot; login form:
<form method=&quot;post&quot; name=&quot;loginform&quot; action=&quot;/login/login_action.asp&quot;>
<table>
<tr>
<td class=&quot;whiteletter&quot;>Username:
</td>
<td><input name=&quot;username&quot; type=&quot;text&quot; size=&quot;5&quot; maxlength=&quot;50&quot;>
</td>
</tr>
<tr>
<td class=&quot;whiteletter&quot;>Password:
</td>
<td><input name=&quot;password&quot; type=&quot;password&quot; size=&quot;5&quot; maxlength=&quot;50&quot;>
</td>
</tr>
<tr>
<td class=&quot;whiteletter&quot;>
<input style=&quot;background-color : white; font-size : 8pt&quot; type=&quot;submit&quot; value=&quot;GO&quot;>
</td>
</tr>

<%
ref_value = Request.ServerVariables(&quot;SCRIPT_NAME&quot
if not isnull(Request.QueryString) then
ref_value = ref_value & &quot;?&quot; & Request.QueryString
end if
%>
<input type=&quot;hidden&quot; name=&quot;ref&quot; value=&quot;<%=ref_value%>&quot;>
</form>

Is Request.QueryString actually null when there is no query string? I seem to always get the &quot;?&quot; at the end of the script name in the browser window. What's wrong?

Thanks

It's never null because it is initialized and contains a null string (a null would mean it had no value whatsoever), you could try doing a length check instead of the isNull function:

If len(Request.QueryString) > 0 Then
