Installing a signed SSL certificate

I am considering use of a CA-signed SSL certificate. Comodo (instantssl.com) offers an "Intranet SSL" certificate good on a single, internal host. All of their documentation refers to set up with a web server or for email verification. Would it also work with FR? There signed certificates are returned as ".crt" files, is this the same as the cert-srv.pem referenced in the self-signed tutorial? TIA, Laker. __________________________________ Start your day with Yahoo! - Make it your home page! http://www.yahoo.com/r/hs
