If you wish a domain only to be proxied on a specific URL, you can set up Exact Match Only to avoid excessive pop-ups on the sub-page of the domain.
For example, if you enable the option for wiley.com domain, Get Access pop-up will only trigger for this domain. It will not be triggered for any of its sub-domains.
To set Exact Match Only, please go to Access > E-resource Domains > if you want to enable this option (turn it to Yes) for the particular domain
Once it is done, the extension will only show an Access Possible pop-up on that exact domain.
