You mean the argument to the function?As ASP is a scripting language, of course you can put variables there. I don't get what problem you are facing now.
FOR EXAMPLE
<% Response.Redirect ("http://www.google.com") %> this works
however,
<% varAddress = 'http://www.google.com' %>
<% Response.Redirect ("varAddress") %>
did not work... instead, it give me http:\\xxx.xxx.com\varAddress
and
<% varAddress = 'http://www.google.com' %>
<% Response.Redirect (varAddress) %>
gave an error

今日种种,似水无痕;
明夕何夕,君已陌路...
