I'm looking to append a string to a URL if it matches a domain (for example &safesearch=strict, if the domain is google.com). Does anyone know if this is possible?
You can use proxy access list rule for that.
At first Enable web proxy; and then transparent web proxy by adding NAT rule.
after that add new rule in proxy access and determine URL by select dst.host and path, select deny action and set redirect-to="new address"
You can use regexp in access list rule dst.host
to improve your network.
