public class HttpLogger
extends java.lang.Object
implements Logger

This class implements Logger interface for HTTP/S persistence. The records are POSTED to the specified URL which must be a web program such as CGI or servlet.

sawt_site=siteName&sawt_type=WT_WAS{&sawt_info=data}+ where data is

See DatabaseLogger class for definition of the fields. If a field is null, a dash (-) will be written in that position. For example, "sawt_site=yahoo&sawt_type=WT_WAS&sawt_info=<01010123-1234> <-><->&sawt_info=<01010123-1235> <-><->"
