Is their any way to display a custom page for HTTP 400 error. I'm using PHP with IIS7 in Windows server 2008 R2
I checked Microsoft website and got this info. It tells that we can't customize it.
I found another article regarding this via ".htaccess" file (http://perishablepress.com/custom-http-errors-via-htaccess/)
No. We cannot display a custom page for HTTP 400 error using PHP in IIS7 in windows server 2008 R2.
