In fact there are two concepts here, and part of what I think confused you is
something I just discovered this week and plan to report as a bug:

Does anyone know how to get syntax->string to recover the original

I'm using Racket 8.0 cs on Ubuntu 20.

If I try to do the more convenient outside position for quasisyntax/loc,
my EOL data seems to get overwritten:

I think that's probably what you want.

Is there a way in racket to obtain the path of the application program?

Thanks Tony,
I can confirm that eof-evt promptly delivers the expected information
about the dropped TCP connection.
Can an application promptly find out about dropped connections from any
available HTTP library for racket?

try testing the input port for closedness two different ways. The
default code tests with port-closed-evt. The commented out code tests by
calling port-closed? in a loop. Neither method succeeds in detecting
the broken TCP connection.
Thanks for any help.

Racket users,
How do I accept an inbound TCP connection so that once I am processing
it, if the connection is broken by the client or network, my program
promptly finds out?
