    The actual pastebin website at https://mathb.in/ is usually a few versions ahead of the source code that is published on GitHub. I have written more about this in the 10th anniversary post here: https://susam.net/blog/mathbin-turns-10.html#source-code (see section "Source Code").

    I have now updated the Nginx configuration to block arbitrary headers coming from the remote client and explicitly pass only a limited set of headers to Hunchentoot. This is a good practice anyway. So now I have added something like this to the Nginx reverse proxy configuration:
