Abstract: A method and system for inserting web content through intermediation between a content server and a client station. An intermediation system within an HTTP communication path between a content server and a client station receives a markup language that is being transmitted via the HTTP communication path from the content server to the client station. The intermediation system then detects a markup-insertion instruction within the markup language and responsively inserts new markup language into the set of markup language, so as to establish a modified set of markup language. The intermediation system then sends the modified markup language along the HTTP communication path to the client station.

Abstract: A method and system for dynamically varying intermediation functions in a communication path between a content server and a client station. An intermediation system within the communication path receives an HTTP message and detects an intermediation-variance instruction within the message. In response, the intermediation system varies a default set of intermediation logic, such as by removing, changing or adding one or more intermediation triggers and/or intermediation actions. In turn, the intermediation system applies the variant intermediation logic in response to the HTTP message and/or in response to subsequent HTTP messages.
