Hi Daniel,
 
the logic is when fastcgi server receive the request from client, it will use curl library send a http request out to another web site. Based on response fastcgi server received, the fastcgi serevr will generate a response to client.
 
when I did test on my lab, it seems works: I mean that the function curl_to_string works well. But when I deployed this into production server which means high volume requests, the client always get 500 error which generated by my fastcgi server.
 
I guess: since fastcgi server is a web server, does the server will be broken if the curl be called from inside? but I really has no idea about it.
         
 
Thanks.
