A method, system and apparatus for managing an interposed reverse proxy. The method can include comparing within a markup language document, a host address for the markup language document and a codebase address for a code base supporting logic disposed within the markup language document. If the host address and the codebase address differ, it can be concluded that a reverse proxy has obscured from view a server source of the markup language document. The method of the invention further can include retrieving a server affinity identifier for the server source from the configuration tags for the logic. Responsive to concluding that a reverse proxy has obscured from view a server source of the markup language document, a tunneled connection to the server source can be attempted through the reverse proxy by inserting the server affinity identifier in an address specified in the attempt.
