1. A system to construct parameterized web documents, the system comprising: a microprocessor to: identify a base document that serves as a reference for a current document; identify strings that occur in the base document that also occur in the current document, and strings that occur in the current document that do not occur in the base document; and create a condensed document comprising a programmatic representation including at least one parsable statement used to modify the base document with at least one string that occurs in the current document that does not occur in the base document, the condensed document configured to be parsed within a content browser to recreate the current document based on the at least one parsable statement and the base document, the programmatic representation condensing one or more of the strings that occur in the current document that do not occur in the base document, the programmatic representation being decodable by a decoder of the content browser, the content browser decoder being configured to perform at least one content browser function unrelated to decoding the programmatic representation.
