Furthermore, in some embodiments, the browser extension 304 operates by detecting that a URL request has been restricted by the RDB 109 as a result of triggering the bypass rules of the RDB 109. The browser extension 304 generates the modified URL request as described above, by replacing the restricted URL portion with an alias URL, not on the exclusion list 302, and forwards the modified URL request to the proxy server 115. In other words, in some implementations, an initial URL request 306 is issued by the RDB 109 and subsequently restricted. The browser extension 304 detects the restriction and generates a modified URL request 308 and forwards the modified URL request 308 to the proxy server 115.
