Hey Monks,

My current company has their entire web application written in Perl using the now defunct CGI modules. I have been tasked with making a 2 factor authentication system for it, and this defunct CGI module is the bane of my existence. I am doing a simple AJAX call passing JSON data back and forth. The first AJAX call is fine, but the second AJAX call breaks the CGI header data and spits out my raw file path to my Perl login function.

I have been running debugging, and the header type is set properly to application/json, yet it is not getting interpreted properly. If I recall, a Stack Overflow post similar to mine seemed to indicate it is a core CGI header caching issue, but I'm genuinely stumped as to what that means conceptually, and what the working solution is. I feel like I can't be the only Perl user stuck using defunct modules trying to use AJAX functionality.

My temporary working solution has just been to call a CGI redirect instead of returning the second AJAX response, but this was a horrific band-aid I don't want to keep.

I suppose my questions are, 1) Conceptually what the heck is going on. 2) How can I manually command this CGI module to not short-circuit and respond with what I actually want?
