Hello Wootie, please read the FAQ or simply read the following quoted from the FAQ.
Which web servers do you support?
We are aware of no incompatibilities with apache 1.3+, IIS 5+ or litespeed 4.0.2+. If there's a web server you feel we should be actively testing (e.g. lighttpd), we're interested in hearing.
If your server is not listed above then you will have to report it and they might look into it for you.
Kind regards
