# JSP Hit Counter Sometimes we need to know how many times a particular page has been visited. In such cases, we need to add a page counter to the page. The page visit count is generally incremented when a user first loads the page. To implement a counter, you can use the application implicit object and its related methods getAttribute() and setAttribute(). This object represents the entire lifecycle of the JSP page. It is created when the JSP page is initialized and deleted when the JSP page calls jspDestroy(). The syntax for creating a variable in the application is: application.setAttribute(String Key, Object Value); You can use the above method to set a counter variable and update its value. The method to read the variable is as follows: application.getAttribute(String Key); Each time the page is accessed, you can read the current value of the counter, increment it by 1, and then reset it. The new value will be displayed on the page when the next user visits. * * * ## Example This example will demonstrate how to use JSP to calculate the total number of visits to a specific page. If you want to calculate the total hits for all pages on your website, you must place this code on all JSP pages.

Total page hits:

Now we place the above code in a file named main.jsp and access the file at _http://localhost:8080/testjsp/main.jsp_. You will see that the page generates a counter, and the counter changes each time you refresh the page (increases by 1 with each refresh). You can also access it through different browsers, and the counter will increase by 1 after each visit. As shown below: !(#) * * * ## Resetting the Counter Using the above method, the counter will be reset to 0 after the web server is restarted, meaning all previously saved data will be lost. You can use the following methods to solve this problem: * Define a data table named `count` in the database for tracking webpage hits, with a field `hitcount` that has a default value of 0. Write the statistics to this table. * Read the `hitcount` field from the table each time the page is accessed. * Increment the `hitcount` by 1 on each visit. * Display the new `hitcount` value on the page as the page's visit count. * If you need to track hits for each page, you can add the code to all pages using the above logic.
