Scan rules are interpreter from the first rule to the last rule. A matching
rule is *NOT* stopping the interpreter, hence:

+www.foo.com/*
-*

Will not mirror *anything*, because the last rule, always checked, will always
exclude everything.

> -www.xmission.com/~*
> -ftp.xmission.com*pub/lists/*
> -mailman.xmission.com/lurker/*
> +stats.xmission.com/linux/o_echo*
> +stats.xmission.com/linux/o_phoneserv*
> +stats.xmission.com/linux/o_pbx*
> -stats.xmission.com/linux/*
> +*.png +*.gif +*.jpg +*.css +*.js

Try this one:

-www.xmission.com/~*
-ftp.xmission.com*pub/lists/*
-mailman.xmission.com/lurker/*
-stats.xmission.com/linux/*
+stats.xmission.com/linux/o_echo*
+stats.xmission.com/linux/o_phoneserv*
+stats.xmission.com/linux/o_pbx*
+*.png +*.gif +*.jpg +*.css +*.js

or, using simpler rules:

-*
+stats.xmission.com/linux/o_echo*
+stats.xmission.com/linux/o_phoneserv*
+stats.xmission.com/linux/o_pbx*
+*.png +*.gif +*.jpg +*.css +*.js
