Re: [PHP] BUG?: header("location: ") causes GET vars to be encodedin wrong charset in IE5.5

I also just noticed that your first variable in the query string (which begins after the ? character) begins with an &, which is a separator character. I'm not sure what's going on there, but it should be something more like this: header("Location: http://192.168.254.14/show_products_html.php

You should always use a proper full URL in the Location header. Try that first. header("Location: http://192.168.254.14/show_products_html.php?&maker_name=$maker_name&PHPSESSID=$PHPSESSID";); I doubt this will solve your problem, but it is good practice anyway. One thing that would help debug
