#:style 'toc]{Scheme Servlet Environment}
The @web-server provides a means of running Scheme servlets
from within DrScheme, or any other REPL.
@file{servlet-env.ss} provides the servlet API from @file{servlet.ss}
as well as the following:
@defthing[send-url (parameter/c ([url string?] [separate-window? boolean?] . -> . void))]{
Should open @scheme[url]. In another window if @scheme[separate-window?] is true.
By default this is from @scheme[(lib "sendurl.ss" "net")].
}
@defform[(on-web servlet-expr)]{This expands to @scheme[(on-web 8000 servlet-expr)].}
@defform[(on-web port servlet-expr)]{
This constructs a small servlet, where the body of the @scheme[start] procedure is
@scheme[servlet-expr], runs the @web-server on port @scheme[port], and calls
@scheme[send-url] with a URL for the constructed servlet. The call blocks until the
servlet finishes its computation, i.e. @scheme[servlet-expr] is evaluated, and
returns its result. @scheme[servlet-expr] may use the entire Scheme servlet API.
(See @secref["servlet"].)
