Abstract
A new uniform resource locator (URL) of file system attachment (FSA) is created on a web browser. The new URL combines features of the URLs of HTTP and "file". The new URL first attempts to attach the file system where the data is stored. If the client has access to the data base or the data storage where the requested information is stored, then the web server may be bypassed by using the URL of "file" and use of the server is not required. If the client does not receive access to the data base or the data storage where the requested information is stored, then the URL of FSA will act like the standard URL of HTTP and access data through the server.

Description
Background of the Invention
1. Field of the Invention
The present invention relates to computer programming and, in particular, to computer software for directly accessing information from a file system with a web browser on the Internet or on an intranet, without accessing the web server.
2. Description of Related Art
Current web browsers processing a URL (Uniform Resource Locator) of HTTP (HyperText Transport Protocol) are all processed by a web server that retrieves the data and sends it back to the requesting web browser on the client. As shown in FIG. 1, when a URL is selected, web client computer 100 sends a request to web server computer 101 to get the web page from data base 103 (on a separate computer) and the web server transmits the web page back to the web client for display on computer screen 102. If the web server is not operating or network 104 is busy, then the web browser on the client system cannot access data that is controlled by the web server. If the web server is operating and the network is functioning, a delay in processing can be caused by having an abundance of requests for data made through the network to the web server.
Only if the client system has access to the data base or the data storage where the requested information is stored may the file be accessed directly. Currently, there is no way of determining whether the web client has access to the storage area, so the overwhelming majority of URL's are listed as HTTP.
Bearing in mind the problems and deficiencies of the prior art, it is therefore an object of the present invention to provide a method for directly accessing information on a file system accessible by a web server without accessing the web server.
It is another object of the present invention to provide a program storage device which embodies an executable program which permits direct access to information on a file system accessible by a web server without accessing the web server.
A further object of the invention is to provide with the aforementioned method a way of determining whether the user has authority to access directly the desired file system.
It is yet another object of the present invention to provide a method of accessing the desired file system if direct access is unsuccessful.
Still other objects and advantages of the invention will in part be obvious and will in part be apparent from the specification.
Summary of the Invention
The above and other objects and advantages, which will be apparent to one of skill in the art, are achieved in the present invention which is directed to, in a first aspect, a process for accessing information on a computer with an inter- or intra-net web browser from a file system accessible by a web server.

Brief Description of the Drawings
The features of the invention believed to be novel and the elements characteristic of the invention are set forth with particularity in the appended claims. The figures are for illustration purposes only and are not drawn to scale. The invention itself, however, both as to organization and method of operation, may best be understood by reference to the detailed description which follows taken in conjunction with the accompanying drawings in which:
FIG. 1 is a schematic of the prior art system of accessing a desired file in a data base through a web server.
FIG. 2 is a schematic of the method and system of the present invention for accessing a desired file in a data base directly, without going through a web server.
FIG. 3 is block diagram flow chart of the preferred steps employed in practicing the present invention.
Description of the Preferred Embodiment(s)
In describing the preferred embodiment of the present invention, reference will be made herein to FIGS. 2 and 3 of the drawings in which like numerals refer to like features of the invention. Features of the invention are not necessarily shown to scale in the drawings.
The present invention provides a way for the web client user to attach the file system of a URL so that the user need not go through a web server when it is not necessary to do so. A URL (Uniform Resource Locator) is the address or location of a file on the web being utilized.
Additional definitions relevant to the present invention are as follows:
HTTP--Internet client/server protocol designed for the delivery of hypertext materials.
FILE URL--Represents access of files from computers on a network.
URL--Is a text string that indicates the server protocol to use in accessing the resource, the internet domain name of the server, and the name and location of the resource on that particular server.
Mount--Program for making the file system available to the web client.
The solution afforded by the present invention is a new URL of FSA (file system attachment) on the web browser. This new URL combines features of the URLs of HTTP and file. The new URL first attempts to attach the file system where the data is stored. Then the data can be processed like the current URL of file and not require the use of the server. This solution would be most useful for intranet applications.
If the client has access to the data base or the data storage where the requested information is stored, then the web server may be bypassed by having the URL of FSA act like the URL of "file". For example, in FIG. 2, a web client computer 200 first determines if the client has access to the desired data base 203 by a file system attachment (FSA), discussed further below. This FSA URL may be resident in the memory of client computer, entered by the user to the computer, or obtained by contact with a web server computer 201 which normally controls access to the data base 203, on a separate system. The FSA URL allows the web client to access the data to be displayed as a web page on screen 202 by having the web client, through the web browser resident on the client system, obtain the desired web page or other information directly from the data base of storage area 203. In order for this FSA URL to be effective, the user must know that the web client has access to the storage area.
The present invention includes information in the FSA URL as to the name of the file system, its location and the means to attach the file system.
An example of a URL of FSA is shown below in Table 1:
After the term "HREF", appears the term "fsa". This designates the file system attachment URL. The start of the "fas" information follows <fsa>. "afs/fishkill/ibm.com/" is the file system name. "ilcr" is the machine identification that is used to access the file system. "mount.exe" is the name of the program that is used to access this particular file system. This program is resident on the web client and is executed on the web client. The program "mount.exe" is representative of many well known and widely available for making the file system available to the web client.
If the file system cannot be attached for any reason, such as the requester does not have the authority to access the file system or the client software to access the file system, then the new URL of FSA will act like the standard URL of HTTP. An unsuccessful attempt to attach the file system will make the client system aware not to make additional attachment attempts for subsequent calls to the file system. Instead, the client system will immediately behave like the URL of HTTP.
In the event the file system is attached, subsequent requests by the client system using the FSA URL will not re-attach the file system since the system will know that the file system has already been attached.
A flow chart of the process used in the present invention is shown in FIG. 3. Numerals in circles indicate connections to like numerals in other parts of the flow charts. The flow chart description is as follows:
300 Start
301 Select the URL. Select the name of the information to be accessed.
302 If first attachment? Is this the first time a request has been made to attach the file system?
303 Mount the file system. Make the file system accessible to the web client.
304 If successful mount: Has the mount of the file system been successful?
305 Web server. If the mount of the file system has not been successful then the URL of FSA now acts as a URL of HTTP. The web client sends a transaction to the web server to access the data base to get the requested web page and then the web server sends the web page back to the client to be interpreted and displayed.
306 Display the web page. The client interprets the web page and displays the web page.
307 If exit? Does the user want to exit?
308 Exit the system.
The computer program or software incorporating the aforementioned steps and instructions may be stored on an otherwise conventional program storage device, such as a semiconductor chip, a read-only memory, or magnetic media such as a diskette or computer hard drive, which is readable and executable by a computer in conjunction with a web browser such as Netscape Navigator. The aforementioned program may be run on a computer in the background while running the web browser. The resulting direct access link between the client computer system and the desired data file on the network computer separate, from the web server, permits the client computer to access the information as if it were on the client computer's disk drive.
Accordingly, the present invention provides an improved method for directly accessing information on a file system accessible by a web server without accessing the web server, while determining whether the user has authority to access directly the desired file system. The invention also provides a method of accessing the desired file system if direct access is unsuccessful.
While the present invention has been particularly described, in conjunction with a specific preferred embodiment, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the foregoing description. It is therefore contemplated that the appended claims will embrace any such alternatives, modifications and variations as falling within the true scope and spirit of the present invention.
