[racket-users] web-server dispatch and places

Hi all, I'm not sure exactly how to phrase my questions, so let me give a bit of background. I have a fairly large (and growing) web middleware application that uses serve/servlet and currently exposes about 90 function URLs, all of the form "/api//". The application grew precipitously an

Re: [racket-users] "bad variable linkage" after restarting handin server under load

Hi! After a new deadline, I got good news and bad news. # Good news I think *this* bug is fixed. Evidence: instead of crashing at the first reboot under load, the server survived to 10-20 automated reboots with the students submitting en masse without never showing the bug. So not only the patch
