Alternative to Response.Redirect

[Colin Steadman]

I'm looping through an array of employee numbers and
sending them to an Oracle procedure for processing. While
I'm doing this I'm updating a <DIV> tag in the browser
with index number of the current array item so the user
knows how far along in processing we are. The ASP looks
something like this:

<div id=messageToUse rTxT>Please wait...</div>

<%
For i = LBound(arrayOfE mployeeNumbers) To _
UBound(arrayOfE mployeeNumbers)

'...Generate and execute SQL
cn.execute SQL

%>
<script language=javasc ript>
document.getEle mentById('messa geToUserTxT').i nnerText
= 'Processing <%=i%> of <%=UBound(array OfEmployeeNumbe rs)%[color=blue]
>';[/color]
</script>
<%
Response.flush( )
Next
%>

This does exactly what I want it to do, but I now get this
error when I try and redirect the user to another page
when the processing is complete:


The HTTP headers are already written to the client
browser. Any HTTP header modifications must be made
before writing page content


According to some posts I've seen in the forum this
happens because I've already written some HTML to the
browser.

I was wondering therefore if there is any way I could
redirect the user to the next page using some other
mechanism? I seem to recall an alternative to using
Response.Redire ct, but I cant remember what it is!

Any ideas?

Thanks,

Colin

You'd have to use a client-side "alternativ e" such as:

location.href=' someotherpage.a sp';

Strange as it seems

Response.redire ct 'someotherpage. asp'

is in fact a clientside action.
Only a browser understanding the header directive,
will execute that code and redirect.
However

Server.transfer 'someotherpage. asp'

is strictly serverside.

Aha! Thats what I was looking for.

However I've since incorporated 'someotherpage. asp' into
the processing one, and it seems to work rather well.

But thanks anyway.
