CGI::Cookie escapes the cookie name if it contains non-alphas. So trying to set a cookie with the name 'foo:bar' sets one with the name foo%3Abar'. This is a good thing. Apache::Cookie doesn't. Unless you're aware of this it leads to interesting bugs where Apache::Cookie doesn't read/write cookies set by CGI::Cookie.
