How can I implement intercept requests and modify the content of a JSP page for SEO?
Here is an example of using a filter to intercept requests and modify the content of a JSP page before it is served to the client’s browser:
In the above example, of the
SeoFilter class implements the
Filter interface, which allows it to intercept requests before they are processed by the JSP page. The
doFilter method is called for each incoming request, and it modifies the content of the JSP page by setting attributes in the
HttpServletRequest object. These attributes can be used in the JSP page to generate meta tags or other SEO-related content.
To use this filter in a JSP website, you would need to configure it in the
web.xml file, like this:
This configuration tells the web server to use the
SeoFilter class to intercept all incoming requests (
<url-pattern>/*</url-pattern>), and modify their content before it is served to the client’s browser.
