If you want to use both a VFP front end and a web browser to call methods on a server side component through HTTP, look into RDS and its associated DataSpace object. RDS is a part of ADO and is intended for passing ADO recordsets, but it seems to also allow passing XML strings as well. This is based on some experiementing I've done in the past. I don't have any production systems uising RDS. Give it a try.
