Hi, I have tested a mod_perl program that runs on my local computer under Windows 2000, Apache 2.054, using the example below. (I have also tried with -c 10 -n 100, and in that case it shows complete requests 100, failed requests 99). In this example it shows: Complete requests: 300 Failed requests: 299 I don't know why, because if I try to open the page in the browser, the page seems to be working fine. Could you tell me why it appears so many "failed requests"?
