Re: question about using the built-in web server

Hi Per,

Thanks for your help, as always.

This doesn't seem to work, as mycode.scm is still not executed, but putting

	(gnu.kawa.servlet.KawaHttpHandler:startServer 8888)

inside mycode.scm does work, or at least works to the extent that the
code in mycode.scm is run, and the server also responds to http
requests.

I did have one problem, however. I tried putting

	(gnu.kawa.servlet.KawaHttpHandler:addAutoHandler "/" ".")

in mycode.scm, before starting the server, rather than using the
--http-auto-handler command-line option. The server starts and is able
to handle requests. However, when I created a file test.scm,
containing

	#<p>Hello, <b>&(request-remote-host)</b>!</p>

and then loaded this file through the web browser, I get "unbound
location request-remote-host" on the server. I didn't have this
problem when using the http-auto-handler command-line option. I'm
assuming this has to do with which environment is accessible from
test.scm, and I suspect I may have similar problems when trying to
communicate between test.scm and mycode.scm.

I *think* I'm ok without this, as everything that I'm doing after
starting the webserver is in response to UI events, but I'll have to
do some testing to know for sure.

thanks,
Alex
