Well, I've nearly finished polishing up the module itself--still some work to do on the testing script, but it is at least functional. The module, however, is not working properly on my machine, and produces failure messages in the logs. I have put the full code, as I intend soon to publish it anyhow, on my scratchpad: Polyglot's scratchpad.

The errors I'm getting look like this: 

[Mon Oct 30 05:11:03.311339 2023] [core:error] [pid 188075:tid 1396602

The "did not send an HTTP header" has nothing to do with the header, but with premature exiting of code execution due to other problems. The "Undefined subroutine" seems to be the issue, and I have no clue why. Once, with a similar error message, I restarted the apache2 server and all was well. But that no longer works on this new message. I am left not knowing whether my apache2 server is at issue, or whether it is this code--but probably the latter. There's certainly no point trying to publish code that is not first functional, so any help on this would be much appreciated.

Blessings,
