hi, I encountered a problem while configured virtual host. My experiment environment is Apache2+fastcgi+php-cgi. I want to implement mass virtual hosting using rewrite rules based on apache rewrite module. That is, for a request url like: http://1000.xyz.com/test.php, apache will translate it to a absolute file path like: $DOCUMENT_ROOT/1000/test.php, and then get this script to execute. And my conf is: * RewriteEngine On* * RewriteCond "%{HTTP_HOST}" "!^www.xyz.com"* * RewriteCond "%{HTTP_HOST}" "^([^.]+)\.xyz\.com" [NC]* * RewriteRule "(.*)" "/%1$1" [PT]* I use inner redirection in order not to expose this detail to users. Besides, I succeeded when I use external redirection, namely the [R] tag instead of [PT] tag. When I use [PT] tag, apache cannot run expectedly. I request a url : http://1000.xyz.com/test.php, error message pops out like: The requested URL /1000/cgi-bin/php.fcgi/1000/test.php was not found on this server. I don't know if this error results from fastcgi, is it the inappropriate config in fastcgi or inevitable problem by using it? Really appreciate your help.
