Reducing overhead in reverse proxy servers when processing web pages

An approach which enables the overhead of performing a task associated with performing a procedure (function) call to be shifted to clients from a reverse proxy server when the reverse proxy server forwards web pages, the content of which may be dynamically created on the clients according to a description (e.g., using Java Script Language). The reverse proxy server may include instructions associated with the description to re-define the procedure call such that the task (in addition to the logic of the pre-defined procedure call) is performed on the clients. For example, with reference to a procedure call containing a URL accessible only within an intranet, the reverse proxy server may insert instructions which cause each client to insert the URL of the reverse proxy server such that any requests for a resource (corresponding to the URL) are passed through the reverse proxy server.
