If the state of information important to the user is not always kept current, it can increase the distrust of shopping by causing confusion and inconvenience to the technically inexperienced user.

Therefore, in view of the fact that important information is not always up-to-date due to the cache function of the browser in the Internet e-commerce system, the present invention may cause confusion to the user. Language Meta Tag, URL (Uniform Resource Locators) Common Gateway Interface (CGI) Common User Interface (CGI) Program using techniques such as URL redirection using dummy pages. Prevents the contents of the user's system cache from being viewed when the browser's Back or Reload buttons are used, so that the latest information is always displayed. Thus, the present invention can increase the convenience of Internet shopping by keeping the main information of the user always in the current state.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exemplary configuration diagram of an Internet e-commerce system to which the present invention is applied. In the drawings, "11" represents a client and "12" represents a web server.

The general user accesses a desired web server 12 through a web browser 111 of a personal computer (PC) and performs necessary tasks. This task may include tasks such as inserting, deleting, and changing data as well as ordinary search and retrieval, which are performed by the interaction between the user and the system, that is, the client 11 and the server 12. In this case, the system dynamically generates a web page for the input and output data of the user. In this case, the technologies used are common gateway interface (CGI), Java (JAVA) servlet, and the like.

The web page dynamically generated according to the user's actions is complicated and causes various cases.

When a user who applies for input, modification, or deletion of data sees the result page through the web browser 111 from the system, the system must be thoroughly prepared for all actions of the user that may misrepresent the result. do.

For example, when a user presses a back button or a reload button on a result screen of data input, modification, or deletion, the user may display a result different from what the user wants. The system must be able to maintain a consistent state at all times, regardless of whether the back button or the reload button is used.

Now, for important information in the Internet e-commerce system such as user information, shopping cart information, order information, delivery information, payment information, etc., the user is always present regardless of the use of the browser's back button or reload button. It will be described in more detail how to show the state of.

The present invention, the process of avoiding the cache function of the browser by inserting the hypertext generation language (HTML) Meta Tag or Web address (URL) system time, and the URL redirection using a dummy page (Dummy Page) (Redirection) involves the user's reload function to be performed as intended by the user.

First, the process of avoiding the cache function of the browser is as follows.

An example of setting the "Pragma No-Cache" variable of the HTML Meta Tag is shown in FIG. 2. This is useful if the information that needs to be kept current at all times is undesirable or dangerous due to the browser's caching capabilities, or if the web page or dynamic web page generator has a "HTTPHEADER: Pragma, No-Cache" value. By default, the web browser 111 does not cache the corresponding page.

In the present embodiment, a variable value is set in the web page to avoid caching the previous information of the web browser 111 so that the web browser 111 does not cache the previous information for the information that needs to be maintained. When the Back button is pressed, the web browser 111 may provide the user with the latest information without caching the previous information for which the variable value is set.

Meanwhile, an example of another method of inserting URL system time to solve the web page cache problem is illustrated in FIG. 3.

In this embodiment, in order to prevent the web browser 111 from caching the previous information for the information that needs to be maintained in the current state, a time variable value that can classify the current date and time in seconds in the address (URL) for each web page. When forcibly inserted and the back button is pressed, the web browser 111 may provide the user with the latest information without caching the previous information based on the time variable value.

If a fixed URL causes a web page to remain in the cache of the web browser 111, when the contents of the actual web page change, the web browser 111 continues to show the cache value so that the user sees the latest information. Problems can arise.

As a way to solve the web page cache problem, as shown in FIG. 3, a variable value (current_time) for dividing the current date and time in seconds for each page is always included.

Then, by forcibly inserting a time variable into the URL of the web page in the web page or the dynamic generation module that calls the page, the web page of the new URL is always found, thereby providing the latest information.

Now, the process of avoiding the original function provided by the reload button of the web browser 111 through URL redirection using a dummy page will be described in more detail with reference to FIG. 4.

In this embodiment, a dummy page is generated and changed to a dummy page address after changing user information on the web page so that the web browser 111 does not cache previous information for the information that needs to be maintained in the current state. If the page implements the function of calling the corresponding web page, and presses the reload button through this, the web browser 111 can ignore the previous information change operation of the web page and provide the latest information to the user. have.

The problem with the Reload button, which prevents the user information retention, is in reworking the previous operation. As a workaround, a dummy page is created after changing the user information of the web page and forced to redirect the URL. By reloading the web page from the dummy page, the reload button ignores previous information changes and only redo URL redirects.

Using this technique, if the reload button is pressed on the web page, the operations such as redirection to the dummy page are re-executed rather than re-added, changed, or deleted, so that the reload button is prevented from malfunctioning. Can be.

The development method thereof will be described in more detail with reference to FIG. 5 as follows.

For someone who develops a dynamic web page that adds, changes, or deletes data, the Reload button on the page that shows the results of working with the data.

Since we duplicate the data work we did before, to avoid this error, make sure that the result screen of the module that does the data work is not visible to the module that creates the original page. In other words, in the module that performs the data operation, when the data operation is completed, it is not sent to the original module, but forcibly branches to the external dummy page. At this time, the dummy page does nothing and branches to the original page. As a result, when the user presses the reload button (or the refresh button), the aforementioned error can be avoided by performing a forced branch to the last dummy page, instead of performing the existing data operation again.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

As described above, the present invention has an effect of increasing convenience for the user by preventing confusion that may occur to the user by keeping the state of the main information always up to date.
