+One challenge I faced was locating the OWASP Top 10 vulnerabilities.
+ I first tried scraping the main OWASP project page, but it
+  did not contain the A01-A10 entries directly. I solved this
+   by inspecting the website and navigating to the OWASP Top
+    10:2025 page, where the vulnerability links were listed.
+
+Another challenge was learning how to use Selenium, XPath, 
+and browser developer tools to find the correct elements.
+ After examining the HTML structure, I updated my script to 
+ collect the vulnerability titles and links and save them to
+  a CSV file.

+I reviewed the Durham County Library robots.txt file.
+
+The robots.txt file allows access to most of the website but restricts access to the /staff/ directory. It also blocks several AI-related crawlers and automated bots.
+
+When collecting data from a website, it is important to follow the robots.txt rules, avoid making excessive requests, and only gather publicly available information.
+
+Ethical web scraping helps respect website policies and reduces unnecessary load on website servers.
+
+I also reviewed the Wikipedia robots.txt file. Wikipedia includes different rules for different user agents and restricts some areas from automated crawling. This shows that websites can allow some crawlers while limiting others.
+
+Robots.txt helps website owners control automated access to their site. Following robots.txt is important because it helps avoid overloading servers and respects the website owner's rules.
