I want to modify query parameters used when accessing a Drupal page. I tried implementing
hook_url_inbound_alter(), but it only allows to parse/modify the path, and it doesn't allow any interaction with the query string.
I see there is also
drupal_get_query_parameters(), which allows to read the query parameters.
I could detect the presence of a query value in index.php and do a string replacement on the value if needed, but I don't want to pollute the front controller.
Do you have any better advice?
