Combination of fullPath and arguments uniquely identify FastCGI process pool definitionPHPRC environment variable contains path to the php.ini file#Per-site PHP configurationConfiguring Handler Mapping
Reference FastCGI process pool by concatenating [fullPath]|[arguments]#Providing URL rewriting
#Manage CPU utilizationWindows Server Resource Manager (WSRM)Available in all SKUs of WS2008Ensures that process gets *at least* the configured CPU percentageKicks in only if overall CPU load is more than 70%IIS team tested with 4000 web sites#Using WSRM
#Best practices summaryFollow IIS 7.0 security isolation guidelinesLeverage FastCGI/IIS features to enhance hosting offer:Multiple PHP versionsPer-site PHP configurationURL rewritingUse WSRM to manage w3wp.exe and php-cgi.exe CPU utilizationMore information at http://learn.iis.net/page.aspx/208/fastcgi-with-php ##Q & A
