using getfield to split up URIs

Hi,

I've got two more questions:

1. will getfield return the whole string if the field delimiter does not exist and the field to return is number one? E.g.:

getfield "/some/path/to/ressource/" "?" 5

Will this return "ressource" ?

2. How exactly does URI:query work? The manual only states "extracts the query part from the URI". I'm not really a webhosting person, but more of a networks guy, so "query part" does not really tell me that much at all...

Thanks and regards,

Martin
