ABSTRACT:
FIELD OF THE INVENTION
The present invention relates generally to computer networks, more specifically to internet data communications, and particulary to the automatic redirection of a digital send to a web page when sending through electronic mail channels becomes restricted.
BACKGROUND OF THE INVENTION
Glossary
The following terms and acronyms are used throughout this document; these definitions are provided for the convenience of the reader; however, no limitation on the scope of the invention should be implied herefrom.
“Client-Server”: A model of interaction in a distributed computer network system in which a program at one site sends a request to another site and then waits for a response. The requesting program is called the “client,” and the program which responds to the request is called the “server.” In the context of the World Wide Web (“www” or “web;” defined hereinafter), the client is a “browser;” a program which runs on a computer of an end-user. A program and network computer which responds to a browser request by serving web pages and the like, are referred to as a “server.” Specialized servers, such as dedicated electronic mail (defined hereinafter) servers are also known in the art.
“Electronic Mail” (“e-mail”): The process and software for sending and receiving of textual information and attachments thereto between end-users over a distributed computer network such as the internet; internet access providers often include e-mail service to its customers as part of the access software that allows the end user to dial into the internet.
“Hyperlink”: An internet navigational link from one document or web page to another, or from one portion or component of a document or web page to another. Typically, a hyperlink is displayed as a high-lighted word or phrase on a web page that can be selected by clicking a mouse screen pointer thereon, resulting in an automatic transfer to the associated document or portion.
“Hypertext System”: A computer-based informational system in which documents or other types of data, are linked together via hyperlinks to form a user-navigable web of network or internet sites.
“Internet”: A generic term for a collection of distributed, interconnected networks (ARPANET, DARPANET, World Wide Web, or the like) that are linked together by a set of industry standard protocols (e.g., TCP/IP, HTTP (defined hereinafter), and the like) to form a global, distributed network.
“Header”: A data string defining the attributes such as size, data format, and the like, of an attached message.
“Hypertext Mark-up Language” (“HTML”): A standard coding convention and set of codes for attaching presentation and linking attributes to informational content within documents; the primary standard used for generating web documents. During a document authoring stage, the HTML codes (referred to as “tags”) are embedded within the informational content of the document; when the document is subsequently transferred from a server to a client, the codes are interpreted by the browser and used to parse and display the document. In specifying how the browser is to display the document, HTML tags can be used to create hyperlinks to other web documents.
“HyperText Transport Protocol” (“HTTP”): The standard www client-server protocol used for the exchange of information such as HTML documents and client requests for such documents between a browser and the server. HTTP includes a number of different types of messages which can be sent from the client to the server to request different types of server actions. For example, a “get” message which has the format GET<URL> (defined hereinafter) causes the server to return the document or file located at the specified URL.
“PULL”: A technology, commonly used as the basis for web communications, in which the client browser must request a specific web page, such as by a hyperlink, before it is sent by a server.
“PUSH”: A technology for information dissemination used by a server to send data to users over a network. PUSH protocols send the informational content to the end user computer, or client, automatically, typically based on information pre-specified by the user.
“Uniform Resource Locator” (“URL”): A unique address which fully specifies the location of a file or other resource on the internet. The general format of a URL is “protocol://machine address:port/path/filename.” The port specification is optional, and if none is entered by the user, the browser defaults to the standard port for whatever service is specified as the protocol. For example, if HTTP is specified as the protocol, the browser will use the HTTP default port; <HTTP://WWW.HP.COM> is a URL, where postfix “.COM” is a commercial entity, “.EDU” is an educational entity, “.GOV” is a government entity, and “.ORG” is a non-profit organization. Hyperlinks are often URL designations.
“Simple Mail Transfer Protocol” (“SMTP”): A standard protocol which provides the mechanism for sending e-mail messages; an electronic mail Server can use SMTP to forward messages.
“Web Site”: A computer system that serves informational content over a network using the standard protocols of the web. Typically, a web site corresponds to a particular internet domain name, such as HP.COM”, and includes the content associated with a particular organization such as Hewlett-Packard Company. The term is generally intended to encompass both (1) the hardware/software server components that serve the informational content over the network, and (2) the “back-end” hardware-software components, including any non-standard or specialized components that interact with the server component to perform service for web site users.
“World Wide Web (“web”)”: Refers generally to both (1) a distributed collection of interlinked, user-viewable hypertext documents (“web documents” or “web pages”) that are accessible via the internet, and (2) the client and server software components which provide user access to such documents using standardized internet protocols. Currently, the primary standard protocol for allowing applications to locate and acquire web documents is HTTP, and the web pages are encoded using HTML. However, the terms “web” and “world wide web” as used herein are intended to encompass future mark-up languages and transport protocols which may be used.
DESCRIPTION OF RELATED ART
The inter-computer communications system known as the internet and world wide web have become a ubiquitous reality more quickly than most previous technology innovations.
E-mail products, e.g., Microsoft™ Exchange Server 5.5 software, run on dedicated mail servers, e.g., the HP™ E60 NetServer computer, are commercially available. In order to control e-mail traffic, many e-mail servers limit the size of e-mail text “messages” or messages and attachments in the form of digital files that can be sent intact, making it problematic to send via e-mail very “large documents” (i.e., an entire informational content data set including text messages, attachments, and the like). Generally in the state of the art a system administrator will set a specified limit for the data set file size about one megabyte as a threshold for allowing unrestricted e-mail transmission. A document is limited to the smallest unit encountered or the message is partitioned. (Hereinafter, the term “LARGE DOCUMENT” is used to mean any message or document which exceeds an e-mail server specified content limit; no limitation on the scope of the invention is intended nor should any be implied from other uses or conventions for this term.)
Image content files, such as photographs, are often much larger than such a specified limit, thus constituting a LARGE DOCUMENT. Similarly, color documents have embedded code for specifying each picture element (“pixel”), in other words, more data per pixel, and thus greatly increase a document data set complete file size. When a server encounters a message having a header indicating that the message or the message and its attachments exceeds the specified limit, the document is either broken into smaller messages or rej
