Abstract: The solutions provide a distributed computing architecture and system for HTTP message exchange and modification. An HTTP request for information may be pre-processed by a first server to detect the geographic location information of the requester and add such geographic information into the request. The modified request is further processed by a second server to identify rules associated with each type of geographic location information included in the request and to add such rule information as associated with the geographic location information into the request. The further modified request is then processed by a third server to determine the geographic location information, retrieve the rule information, and map and obtain a content customized for the request based on the geographic location information and the rule information.
