so i found my solution, wp-blog-header is not needed.

in my ajax i was calling the php page directly when i need to go through /wp-admin/admin-ajax.php. this is the most elegant solution because it will also take care of authorization.

in jquery this looked like:


function updateProduct(name, value) {
jQuery.post(
"/wp/wp-admin/admin-ajax.php", {
action: "update_product",
'cookie': encodeURIComponent(document.cookie),
'name': value
},function(msg) {
jQuery('#debugger').append(msg+'
');
});
}


then in my plugin top page i added an action


add_action('wp_ajax_update_product', 'updateProduct' );


and then the function to access the database as per the action:


function updateProduct() {
global $wpdb;
$table_name = $wpdb->prefix . "ajax_test";
$query = "INSERT INTO $table_name ($insert_key) VALUES ($insert_value)";
}

exit;
}
