CGI, FastCGI and ISAPI

which to use on server migration

[AWildman]

So, we're going to be upgrading our web server with a new server. We need to install php to run some apps. Currently, we have IIS and use ISAPI. Our new web programmer suggested that we move to FastCGI. Anyone done that yet? Any performance issues? Will we have to rewrite apps to use FastCGI? We currently are WAY behind on php, as in I haven't updated it in 3 years. I've read a few articles which basically said that FastCGI was the wave of the future...but is it stable and ready to use NOW?

I tried FastCGI in a shared hosting environment and my .htaccess code was messed up. I got many Internal Server Errors 500 and my website was basically useless. I switched back to CGI to undo the mess. Well, I might've had no luck when I switched to CGI, but you might experience something different if you do the same.

Just make sure you TEST YOUR APPLICATION in a FastCGI environment before completely changing your server or your website might be offline for a few hours, until you switch it back. Make sure EVERYTHING works. PHP Scripts and specially .htaccess mod_rewrite Apache commands.

Sorry I couldn't be more helpful, but I do wish you good luck. FastCGI does seem a lot faster, but I haven't switched to it yet because as I said my application is disfuntional with it. That might just be a problem with my hosting company.

Thanks for the information. I'm not the one doing the migrating, but I have warned that person to be diligent about testing out all of our applications in the new environment.
