Is it unreasonable to expect this to evaluate to null?

Did this go anywhere? It would definitely be cool to see DrRacket in
the Ubuntu Applications menu.
A screenshot in the Ubuntu Software Center would be nice too, but I
don't know where that comes from (doesn't seem to be part of the
.desktop file). Oh hm, does it get them from
http://screenshots.

I don't want to run a single servlet, I want to run a web server (via
plt-web-server) with many #lang web-server servlet modules.

I wanted to know how the Racket web server figures out whether a URL refers
to a servlet or not. In particular, I was curious about how the
"servlet-root" path in the configuration table was used (its default is
"."). The closest thing I could find to documentation was this bullet point
in the do
