A World Wide Web (Web) distribution site for accessing a plurality of Web documents from a database through a distribution system comprising a plurality of server computers of different computer powers wherein server computers are designated for documents based upon document weights calculated for the Web documents. The system has means for determining a document weight for each of said plurality of Web documents, which include means for counting the total number of bytes of 15 data representing the content of each of said documents, means for assigning a complexity weight to programs in each of said plurality of documents, and means for multiplying the byte total for each Web document by the complexity weight of the Web document. Based upon said 20 document weights, the system provides means for designating the server computers for said respective Web documents. The server system at Web distribution sites automatically periodically monitors the Web documents for 25 significant changes in content resulting in document weights, and adjust its applied server computer resources to effectively cover such changes in content for the Web documents managed through the distribution site.
