A method is disclosed for determining a location of a client session in a telecommunications network by comparing attributes of the client session connection to location definition information stored in a configuration file. A method of handling requests from proxy and non-proxy client connections in a telecommunications network by redirecting requests from unauthenticated proxy clients to a transparent proxy port on a captive portal such that the captive portal proxies the requests is also disclosed. The request may be directed to a service, such as a destination IP address and optional port number. A method for a proxy server to identify an edge session through an out-of-band request containing proxy metadata to a web portal for secure (HTTPS) requests is also disclosed. The edge session is identified for the web portal through a hostkey determined by the proxy server.
