Some browsers include an exclusion list of host URLs for security reasons. These browsers do not forward traffic requests for accessing host URLs on their exclusion list. For example, some browsers do not forward requests to access localhost servers to a proxy. In computer networking, a localhost is a host name that refers to the computer that is executing a program. The term is used when making a loopback request to the same computer. In other words, the localhost is a server running on a machine that is only accessible from that machine and refers back to the machine. Software developers use localhost and localhost servers to test and develop their programs. The IP address of a localhost is “127.0.0.1”. In other words, typing localhost in the address bar of a browser sends a request from the browser to the “127.0.0.1” IP address. In the infrastructure 100, some user's selection of RDB 109 do not forward URL requests to access a localhost to the proxy server 115. A browser exclusion list can be alternatively referred to as the implicit bypass rules of the browser. When the browser's implicit bypass rules might otherwise prevent a user developer to issue a traffic request from the RDB 109, the infrastructure 100 can modify the URL of the traffic request to avoid the exclusion list or implicit bypass rules of the browser.
