Something like this should work: 

when RULE_INIT {  set static::old_host "www.abc.com"  set static::old_path "/uri/oldpage.aspx"  set static::new_host "www.xyz.com"  set static::new_path "/uri/newpage.aspx"}when HTTP_REQUEST {  if { ([HTTP::host] equals $static::old_host) && ([HTTP::path] equals $static::old_path) } {    set n [HTTP::query]     if there is a GET variable assignment, you'll need to query the value as such     set n [URI::query [HTTP::uri] "some_get_var"]    if { [string length $n] != 0 } {      set redirect_url "http://${static::new_host}${static::new_path}?${n}"
      HTTP::redirect $redirect_url      log local0. "Redirected client [IP::remote_addr] to $redirect_url"    }  }}

Fill in the static variables in RULE_INIT and it should work for your situation. If you need to pull a value from a GET variable in the query section you might need to modify it slightly (see the commented section).
