Today i visited oauth.net and found following error.

LiteSpeed is a paid web server, that says much faster than free apache web server. I think it is better using open source apache than using LiteSpeed as apache code is opensource and any one can fix the bug and even make it fast. There are many experts out there who can fix problems. I use Apache for most of my web sites, use lighttpd for static files and ngnix for load balancing.

It is bad LiteSpeed showing link to their site like an advertisement when unfortunate error happens. Every time your site crash, litespeed get more visitors and more sales ?
