Hi Andy,

Try looking at the comments in the header file HTTP.h

I think your 100-continue's are coming from the default
_HTTPConnectionMode HTTP_11_PIPELINING,
try setting: HTTP_setConnectionMode(HTTP_11_NO_PIPELINING); or even more
drastic
HTTP_FORCE_10 to turn off the HTTP 1.1 persistent connection, pipelining
feature.

On whether the server and XSQLPages should support this, I am not sure
though since
Jigsaw reports it supports HTTP 1.1 I would think it would support
continues...
I know when I am using Apache Tomcat 3.2 servlet engine I need to use
the mod_jk and not the mod_jserv
module in order for HTTP 1.1 persistent connections to work properly for
me...

Hope this helps,
Jeff
