I wonder if the problem may be that the browser is caching the result of
the last call to the CGI?
On the server side, any CGI (whether it be LC Server, PHP, Python, or
any other engine) is launched, executes, and dies with each request.
As such, environment variables can't help but be fresh, as the process
is not persistent between requests.
As a diagnostic step I would use a browser's debugging tools to watch
that request carefully.
If your API expects only LC clients without supporting generic browsers,
the detailed logging option for libURL may be helpful, using a spare
field to display some of the transaction details:
https://livecode.com/resources/api/#livecode_script/liburlsetlogfield
You may also consider the old trick of appending the URL with a random
string in the non-actionable part of the URL beyond a hash tag, e.g.:
https://someserver.com/cgi-bin/myscript.lc#123456789
...where "123456789" is the millisecs, so that each request is seen by
libURL as unique (which I believe also works with tsNet; Charles may
have additional guidance).
