Same Website Crawl: Static vs Dynamic Database (e.g. PHP or ASP)

• Using virtual directories with URL rewriting? Site crawlers do not care if directories in URLs are physical on the disk or virtual.
  
  
• Websites using Cold Fusion, ASP.Net, JSP, PHP etc. as server side language has no consequence. Website crawlers only see the HTML generated by the server-side language.
  
  Note: In settings, the crawler in our site analysis tool can be set to accept/ignore URLs with certain file extensions. If you have troubles, read about finding all pages and links.
  
  
• Sites dynamicly generated by scripts and databases are crawled without problems by site crawlers and robots.
  
  Note: Some search engine robots may slow when crawling URLs with ?. However, that is mainly because search engine are worried spending crawling resourced on lots of URL with auto generated content. To mitigate this, you can use mod rewrite or similar in your website.
  
  Note: Our sitemap generator and the MiggiBot crawler engine does not care about how URLs look.
  
  

Normally, websites never cloak content based on user agent string and IP address. However, by setting the useragent ID, you can check the HTML source search engines and browsers see when retrieving pages form your website.
