Hi, i was thinking of the whole picture of baptiste solution, you say :
"Baptiste: On the new linux hosting set up an .htaccess file in the root of the site directory that redirects all id=xxxx requests to a redirect.php file on your server. The redirect.php file will need to interrogate a database with a table of the mappings and automatically redirect to the correct page via php scripting."
it means that wiithout any credentials, any database access, if you have urls from the site you need to move to, you can redirect any urls site to another one !?
Hum..i think i miss something ..
