To add a robots.txt file in Tomcat 7, you can place it in the root of your web application.
Here are the steps to do so:
- Create a new file called "robots.txt" in the root directory of your web application. This is typically the "WEB-INF" folder.
- Open the robots.txt file in a text editor and add the desired rules for web robots to follow.
- Save the robots.txt file.
- Restart Tomcat to apply the changes.
Ensure that the robots.txt file is accessible to web robots by verifying its URL, such as http://your-domain.com/robots.txt.
