Today i encoutered this trouble...
move a website from asp to PHP.... the new server doesn't have asp installed
the problem comes when thinking of many pages linked from search engines and other portals to inner website pages,,,, that will lose their counter part....
e.g. www.mysite/mypage.asp?id=23423 as an answer of google search will not find anythig...
so looking around someone suggested me the mod_rewrite technique setting up
the .htaccess file on the Linux server....
do you have a better solution for this?
