Comment on Dynamic URLs vs Static URLs SEO by Le.

SEO URLs Is there a specific footprint to look for when trying to determine static (html) pages versus dynamic (php or asp) pages? I ask since mod_rewrite is used by dynamic pages to appear static. Since the search engine robots know the difference, I’d like to know to. Would I be able to find this code in the source code? I know that the footprint for WordPress is easily found in the source code.

Thanks in advance
