Detailed solution to the PHP running timeout problem under IIS+fastcgi_PHP tutorial

Whenever I upload a larger file on the page, I encounter a FastCgi error: "The FastCGI process exceeded configured request timeout". After several experiments, I understand that I need to modify the FastCgi configuration file "fcgiext.ini ", located in the directory "C:/WINDOWS/system32/inetsrv".
Add some parameters under the final php configuration content of "fcgiext.ini", as follows:
Quote
[Types]
php=PHP
[PHP]
ExePath=C:/PHP/php-cgi.exe
InstanceMaxRequests=10000
EnvironmentVars=PHP_FCGI_MAX_REQUESTS:10000
RequestTimeout=500
ActivityTimeout=900
If you encounter " The error "FastCGI process exceeded configured activity timeout" is also solved in this way.
