With Netscape all works wonderfull but with Internet Explorer, I get the dumb default error message like ERROR 500... nothing more... no line error, no description... nothing!!!!! But if I put in the custom error message, a file like error.htm... now it works!!! MS can't even make is own products works togeter!! or maybe i'm dumb and I forgot to do something... help me please!
